Abstract

This study examines the influence of the application of a rotating magnetic field in the electrodeposition of copper (Cu). During the electrodeposition, five constant magnets were rotated (500 and 800 rpm) towards the bottom of the sample. To investigate deposition rate, surface morphology, phase, structure, corrosion resistance, and hardness in deposited Cu using a weighing scale, a scanning electron microscope equipped with energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), potentiodynamic polarization, and hardness tester respectively. Bacterial activity was also evaluated through this research. Morphological surface observations showed that the increase in the rotational speed of the magnets during the electrodeposition process led to a smooth surface. A perfect Cu phase covers Al alloy with no oxide. The potentiodynamic polarization demonstrated by the increase in the rotating led to a shift to the more positive value of the corrosion potential. Moreover, the corrosion current also decreases with the increase in the rotating speed of the magnets. Less crystallite size promoted forming a higher hardness and inhibition zone of the Cu films.

Abstract

Metal plating frequently employs nickel (Ni) and copper (Cu) as anodes. Cu/ Cu-Ni film formed has many advantages, such as better corrosion resistance and high hardness characteristics. This study aims to assess the properties of Cu/Cu-Ni film, such as phase, surface morphology, crystallographic orientation, hardness, corrosion analysis, and contact angle, which were fabricated using electrodeposition with various Ni salt additions (0.3, 0.5 and 0.7 M). In addition, the cathode current efficiency (CCE) and deposition rate of the Cu/Cu-Ni electrodeposition were also investigated. An increase in Ni salt in the plating bath could enhance the pH, promoting higher CCE and depleting hydrogen evolution at the cathode, leading to the presenting Ni phase in the alloy. The higher concentration of Ni salt in the solution could also enhance the deposition rate due to a shift to a pH value, which affects the roughening of the surface morphology, promoting a higher contact angle. All crystal structures generated by Cu/Cu-Ni electrodeposition were FCC, with the preferred orientation of the (111) plane. Crystallite size and lattice strain depend on the deposition rate. Less crystallite size and lattice strain affect the film’s hardness and corrosion resistance. Moreover, the third bath had the resulting Cu-Ni layer with the best hardness and corrosion rate of around 136 HV and 0.081 mmpy.

Abstract

The use of shielded metal arc welding (SMAW) equipment to synthesize alloys is one of the most promising methods as it can be used for in-situ fabrication. The hardness and corrosion properties of the deposited layer during the welding process can be enhanced by dilution of nichrome (NiCr) during the process. Therefore, the alloy was synthesized on the surface of the mild steel using SMAW equipment with various NiCr additions. The properties of the alloy were investigated using an X-ray diffraction (XRD), an Optical microscope, a Potentiostat, and a Vickers hardness apparatus. The appearance of martensite overlaps with the ferrite phase could be affected by the addition of NiCr to the alloy. An increase in NiCr content is followed by an increase in the lattice parameter value of the ferrite phase. The presence of a certain amount of nickel (Ni) contributes to the formation of lower transformation phases, including martensite. At the same time, the incorporation of chromium (Cr) also plays a significant role in promoting the formation of acicular ferrite. An increase in NiCr content in NiCr2 and NiCr3 samples results in a quantitative increase in martensite formation. Adding 0.434 g of NiCr to the weld deposited layer could result in the corrosion rate of the alloy being 0.1118 mm/y. Higher hardness is found in the NiCr3 sample, around 742.06 HV.

Abstract

The oxygen vacancy properties are significant, creating ferromagnetic properties of material in metal oxide systems like dilute magnetic semiconductors. An aqueous sol-gel method has been used in the present study to synthesize non-stoichiometry BaTiO3-x polycrystalline. In an attempt of examining the oxygen deficiency consequences on the magnetic properties, the gel samples were sintered (1000◦C) at various times (6, 12, 18, and 24 hours) under a vacuum environment. This study employs an X-ray diffraction apparatus in terms of characterizing segments and structures of the samples. It also investigates morphology and element distribution on the surface of the samples exploiting an Electron microscope where Energy dispersive spectroscopy is supplied. For the purpose of characterizing the magnetic properties of the samples, it applies vibrating sample magnetometers. The chemical state of the element and its corresponding bond to other elements was identified using X-ray photoelectron spectroscopy. Single-phase compounds were observed. The crystal system is tetragonal, but the crystal parameters are different. Increase sintering time leads to increase crystallite size and decrease in micro strain. Moreover, sintering in a vacuum environment results in oxygen deficiency and leads to the atomic ratio of Ba/Ti change as the sintering time increases. The Ba/Ti ratio change affects the transformation from diamagnetic to ferromagnetic-like. The elements (Ba, Ti and O) chemical state is shown and its bonding to the corresponding element along with the X-ray photoelectron spectroscopy pattern of the BTX2 sample. The element of oxygen binds to Ti and Ba while Ba element exists in two chemical states.

Abstract

Conventional epoxy coating for surface metal corrosion protection reported many unsolved technical problems. Adding filler in the epoxy could enhance the promising properties of the composite coating. Our work describes in detail the synthesizing and characterizing epoxy/carbon composite coating. Epoxy was mixed with thinner high gloss (HG) and hardener and stirred using a stirrer apparatus. After blending, various carbons were added (1 wt. %, 3 wt. %, and 5 wt. %) and then appropriately stirred. The different mixture composite was coated onto the steel plate cold rolled coiled (SPCC) plate using high-volume low-pressure (HVLP) in two passes. Various characterizations were performed, including crystallographic orientation, Infra-Red (IR)-spectra, surface morphology, thickness, hydrophobicity, hardness, and corrosion using X-ray diffraction (XRD), Fourier transform infrared (FTIR), Scanning electron microscopy (SEM), portable dry film coating thickness (DFT), digital camera, Vickers microhardness tester, and Potentiostat, respectively. More carbon micron-sized content led to elevate the peak intensity, surface bumpiness, and hydrophobicity. The uppermost external bumpiness and hydrophobicity values are 23.51 µm and 101◦. Hardness depends on carbon content and more carbon leads to an increase in the hardness of the composited coating. The highest average Vickers hardness value is 28.24 HV. The coating thickness influenced the corrosion rate, more coating thickness promoted lesser corrosion rate. The highest coating thickness (60.8 µm) promoted a corrosion rate of around 5.65×10−4 mmpy.

Abstract

Nickel (Ni) doped in the perovskite manganite could result in superior properties. The effect of the Ni on the morphology, crystallographic orientation, and magnetic properties of La0.7Sr0.3Mn(1-y)Ni(y)O3 alloy (y = 0.1, 0.3, 0.5, and 0.7), therefore, was undertaken. La0.7Sr0.3Mn(1-y)Ni(y)O3 alloy was firstly processed using a ball milling process, and again processed through heat treatment and crushing at the end of the synthesis process. Powder alloy was then investigated using a scanning electron microscope equipped with scanning electron microscope and energy dispersive spectroscopy (SEM-EDS), x-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The particle size became smaller and agglomerated as the amount of Ni doping increased. The polycrystal structure phase formed would become more complex when the Ni doping was 0.5 and 0.7, where the dominant phase formed was La2NiO4 even though the La0.7Sr0.3Mn(1-y)Ni(y)O3 phase was still formed. The magnetic characteristics showed that the Ni doping of 0.1 had a higher magnetization value around 4.2 emu/g at room temperature.

Abstract

Waste lubricant oil is always found in motor vehicle repair shops. Utilizing waste lubricant oil by distilling it will provide benefits. For this reason, waste lubricant oil was distilled in this research. Several characterizations were conducted to determine the viscosity, density, low heat value (LHV), and flash point of waste lubricant oil and distillation products. The distillation product is less viscous, denser, LHV, and flash point than lubricant oil waste. The distillation product was mixed with Pertamina DEX (0, 5, 10, and 15 vol.%) and then filled into the fuel tank for the engine performance test. The present experiment utilized a compression-ignition (CI) engine to measure performance. CI engine speed variations were carried out at 1000, 1500, 2000, and 2500 to see the influence of the mixed fuel on torque, power, specific fuel consumption (SFC), thermal efficiency, and smoke opacity. The increase in CI engine speed leads to an increase in torque, power, thermal efficiency, and smoke opacity, but at the same time, SFC decreases to 2500 rpm. Increasing the distillation product content in the mixed fuel decreased torque, power, SFC, thermal efficiency, and increased smoke opacity.

Abstract

Cu-15Zn alloy is widely used as a heat exchanger pipe. CuZn alloy was also used for cardiovascular implant applications. Several problems have been found in that alloy, such as less corrosion resistance. Therefore, various Sn (0.2, 0.7, 1, and 2 wt.%) were added to Cu-15Zn alloy in the present research to enhance corrosion resistance. Afterwards, the alloy was homogenized at 800 °C for 2 hours. Several investigations were conducted, such as structure, microstructure, hardness, corrosion resistance, and bacterial activity, using XRD, Optical microscope, Vickers hardness, Potentiostat equipment, and Digital camera. More Sn content leads to an increase in volume and a decrease in hardness. Presenting Sn in the alloy does not influence the phase in the alloy microstructure. The highest Sn content in the alloy promoted a more positive value of the alloy, indicating that the sample is more cathodic, probably due to the protective layer on the surface. A concentration of 1 wt.% Sn exhibits the most effective antibacterial effect probably due to the small crystallite size.

Abstract

Hardness is a mechanical property that is needed when doing the hardfacing process. Increased violence can be generated by conducting a quenching process. The temperature of the quenching media is one of the important factors to produce maximum hardness. In this study a two-layer welding process will be carried out using HV 350 electrodes on low carbon steel then the specimens are heated in a furnace and quenching is carried out into water with two variations in water temperature namely 15 and 30 °C. Variations in water temperature during quenching produce varying hardness and microstructure. The highest hardness is produced at 15 °C where in micro photographs there are a few phases of smaller size compared to other specimens.

Abstract

The SMAW process is a commonly used metal joining method because it is very practical in its use, less cost, and easy availability of equipment. The SMAW process is also easy to operate and can be used in all welding positions. The problem that often occurs in steel construction lies in the welded joints. Therefore, it is necessary to increase the mechanical properties by adding nickel(Ni) to the welded joints. In this research,  electrodes E 6013 and steel of ASTM A 36 was used. The tensile tests, bending tests, hardness tests, macrostructure, and microstructure will be carried out to see changes in mechanical properties. The addition of Ni contributes well to mechanical properties. The tensile strength, face bending, side bending, and hardness increased by 27.6%, 14.5%, 4.8%, and 20.9%, respectively. In the observation of the macrostructure, the porosity was not visible in all samples, while in the microstructure observation, ferrite and pearlite phases were formed in all samples.
