Journal of Material Processing and Characterization (JMPC)
Journal of Materials Processing and Characterization (JMPC) is an international, open-access and peer-reviewed journal aimed to facilitate researchers in disseminating their research works in the field of processing and characterization of engineering materials as well as biomaterials for biomedical applications. In general, JMPC covers all the research topics related to the processing (such as material preparations, fabrication techniques, post-processing treatments) and characterizations (such as novel methods for characterization, experimental testing and numerical analyses) of metals, polymers, ceramics and composites. To be more specific, the journal covers the following research topics: - Processing technologies of engineering materials and biomaterials, including casting, solidification, forming, forging, hot and cold-working, machining, powder metallurgy, extrusion, heat treatments, additive manufacturing, welding, and injection moulding. - Surface treatments of engineering materials and biomaterials, including coatings, shot and grit blasting, anodization, physical and chemical treatments. - Characterizations of engineering materials and biomaterials, including microstructural analysis, surface characterizations, mechanical testing, electrochemical characterization and tribological testing. - Failures of engineering materials and biomaterials, including fractures, fatigue, corrosion and wear.

<![CDATA[Curcumin possesses anticoagulant, anti-proliferative, and anti-inflammatory properties and is applicable to prevent in-stent restenosis. This research investigated curcumin coating with biodegradable chitosan polymer as a drug carrier universally made on Co-Cr L605 surface by the ultrasonic spray method. Three curcumin doses were implemented: low dose (150 μg of curcumin per sample), medium dose (300 μg of curcumin per sample), and high dose (480 μg of curcumin per sample). The metal surface morphologies before and after coating were examined by using a stylus profilometer and a scanning electron microscope (SEM). The result showed that coating films were formed fine and uniform with an average roughness level below 0.2 μm. The coating film structure characterization by Fourier-transform infrared (FTIR) spectroscopy showed that curcumin absorption spectra still occurred in the chitosan-curcumin coating, although chitosan strong absorption spectra were dominant.]]>

<![CDATA[Crusher is a component of heavy equipment used to break rocks or solid materials into a needed size. Crusher that is made of high chromium white cast iron will endure friction and impact forces. The quality improvement of the crusher is needed for enduring its service life. This research is conducted to determine the influence of heat treatment on the wear and impact resistance of the crusher. The material used in this research was high chromium white cast iron with some main compositions such as 18.5%wt Cr, 2.1%wt C, and 2.8%wt Ni. The heat treatment carried out was austenitization at a temperature of 1000ºC, followed by the quenching, quenching-tempering, normalizing, and annealing process. The tests carried out for the characterization of mechanical properties were Vickers hardness, impact, and wear rate. Meanwhile, observation was conducted to examine the microstructure of the specimen. Based on the observations, the microstructure of the specimen is dominated by M7C3 eutectic carbide, retained austenite and martensite. The highest hardness of the high chromium white cast iron (788 VHN) is a specimen with austenitizing-quenching (up 16% compared to normalizing specimens) and gradually decreases (up to 12%) after the 450ºC tempering. The highest wear resistance (8.1E-6 mm³/kg.m) is the specimen with tempering at 450ºC. The highest impact strength (0.055 J/mm²) occurs in the normalizing process. Hence, the heat treatment that can produce optimal properties to be applied in the crusher is tempering with the temperature of 450ºC.]]>

<![CDATA[A solid freeform fabrication technique, aqueous based extrusion fabrication (ABEF), was investigated for the creation of three-dimensional lattice Hydroxyapatite scaffolds with pre-designed pore properties. An aqueous based Hydroxyapatite paste was extruded through a 0.8 mm nozzle, and deposited layer-by-layer at room temperature according to a computer-aided design (CAD) file. The morphology of green body and sintered body were characterized using digital microscope. The phase purity was analyzed using XRD. Fourier transform infrared spectroscopy (FTIR) was performed in order to understand the phase changes upon heating process and to determine HA stoichiometry. The current investigation confirms the possibility of producing three-dimensional lattice Hydroxyapatite scaffolds without any impurities as indicated by XRD and FTIR techniques. The morphology analysis of the structured macroporous Hydroxyapatite bioceramic shows interconnected macro pores and micro pores. It will give possibility for colonization of osteoblast in the pores, fibrovascular ingrowth and finally the deposition of new bone formation.]]>
