Abstract

Aluminum is a type of metal lightweight and easy to shape so it is widely used for several applications including vehicle wheels. The surface of vehicle wheels needs a certain roughness/smoothness to be more aesthetically appealing and production defects during the manufacturing process can be reduced. Anodizing on aluminum has been studied before, but so far there are still not many studies that specifically analyze the results of anodizing on surface smoothness. The purpose of this study is to analyze the roughness of aluminum anodization results when varying the immersion time. Results of this study are compared to the standard roughness of vehicle wheels. The method used is the anodizing process with variable anodizing times of 40, 45, 50, 55, 60, 65 minutes. Then surface roughness testing was carried out using a roughness tester. The results showed that anodizing time plays a role in determining the surface roughness / smoothness of the material. The longer the anodizing time the rougher the resulting surface. The best roughness value occurs in the 40-minute time variation with a roughness value of 0.7683 µm and can meet the DIN 3760 quality standard. With this information, an alternative material to replace vehicle wheels The purpose of this study is to analyze the roughness of aluminum anodizing results by varying the soaking time. The results of this study were compared with the standard roughness of car wheels.

Abstract

Thermal spray arc is a familiar coating method used around 100 years ago. This coating technique was chosen to reduce damage and improve the surface quality of materials with coating bonds that are in direct contact with extreme marine environments. The minimum thickness of the TSA coating is around 100 – 500 µm. According to NACE/AWS/SSPC, a coating layer submerged in seawater will lose 20 µm every year, for a minimum bond strength of 6.89 Mpa. The research aims to analyze the effect of coating distance on AISI 1020 steel. The tests carried out are dry film thickness, pull of adhesive, and bending tests. This research uses distance variations of 150 mm, 250 mm, 350 mm. The research results show that the use of distance has an effect on the bond strength of the layer and the substrate. The best bond strength and bending ability values ​​were found at a distance of 350 mm, with a coating strength of 10.81 Mpa and no bending cracks. Increasing distance variations in the thermal spray process increases bond strength and bending ability.

Abstract

Electrical twin-wire arc spray is often used as protection from material components. The coating process aims to protect the coating from environmental disturbances. The quality of the coating yield is indicated by corrosion resistance. The spraying distance in the thermal spray process will affect the corrosion rate, morphological structure, and thickness. The purpose of this study is to analyze the effect of distance variations in the electrical twin-wire arc spray process with an aluminum coating on corrosion rate, morphological structure, and layer thickness in AISI 1020 steel. Tests are carried out for corrosion tests, scanning electron microscope (SEM), and layer thickness. The implementation of the study used experimental methods using distance variations of 150 mm, 250 mm, and 350 mm. The results of the study of the lowest corrosion rate value at a distance of 150 mm are included in the good category with a value of 0.13667 mmpy, the morphological structure of the layer using a closer distance obtains a smooth and dense layer, then for the highest layer thickness at a distance of 150 mm with an average of 317.16 μm.

Abstract

Thermal spray aluminum is one type of engineering technology in coating. The main property that indicates the quality of the thermal spray result is resistance to corrosion. Thickness, composition, and morphological structure are very influential things about the rate of corrosion. The long parameters of spraying in the aluminum thermal spray process will affect the corrosion rate, thickness, morphological structure, and coating composition. The aim of this study is to analyze the influence of spraying time on corrosion rate and morphological structure of coating layer in AISI 1020 steel. The types of tests performed are corrosion rate testing, Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS). The study used an experimental thermal spray method using time variations of 5 seconds, 10 seconds, and 15 seconds. The results of the study showed that values of corrosion rate, thickness and morphological structure of the coating are best present in spraying using a time of 15 seconds.

Abstract

Thermal spray aluminum (TSA) is a coating method used to resist corrosion, abrasion and deformation. TSA coating applications must have a minimum thickness of 80-100 µm, while for applications at temperatures of 600 – 9500 C the minimum thickness is 200 – 250 µm. The TSA layer in a position submerged in sea water will decrease by around 20 µm every year. The aim of this research is to examine variations in spraying time of 5, 10 and 15 seconds on the adhesion of the TSA coating layer. The substrate material used is AISI 1020 steel, using the #60 sandpaper hand tool surface preparation method. The preparation results were tested for cleanliness of the test samples referring to surface cleanliness ISO 5801. Surface roughness testing in this study produced a roughness of 1.852 µm. The results of the DFT test show that the longer the spraying process increases the layer thickness. The results of the pull off test show that optimal bonding results occur at a variation of 10 seconds with a strength of 8.16 MPa. In the bending test results variations of 5 and 10 seconds did not show any cracks, while in the 15 second variation there were small cracks, but based on standard practice item No. 21100 bending test no cracks and small cracks are still allowed.

The Shield Metal Arc Welding (SMAW) welding technique is the main alternative in working on steel construction on light vehicle frames. The mild steel used is a low carbon content steel which is known to have good mechanical properties. The purpose of this study was to analyze the results of SMAW welding with variations in the thickness of mild steel on the results of the tensile strength test and damage to the material after the tensile test was carried out. The research method used SMAW welding with a current of 35 A and E6013 electrodes and variations in material thickness of 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm and 3.0 mm. The test standard used is ASTM E8. Based on the research that has been done, the results of welding on 1.0 mm thick material having the highest tensile strength of 360.206 MPa, and 1.5 mm thick material having the highest tensile strength of 326.653 MPa, and 2.0 mm thick material having a tensile strength the highest tensile strength is 491,800 MPa, and the 2.5 mm thick material has the highest tensile strength of 416.481 MPa, while the 3.0 mm thick material has the highest tensile strength of 405 MPa. The greatest tensile strength is obtained when the material is 2.0 mm thick, while the smallest tensile strength is obtained when the material is 1.5 mm thick.
