“…The samples were then consolidated by the plasma sintering process method. Special Arc Plasma Sintering (APS) apparatus was used to consolidate the samples using the plasma heat source [10,11] for 20 minutes with 12 V 70 A. The apparatus consists of the arc plasma source generated by the DC pulsed source as the main component.…”

Synthesis of Fe-Cr-Al alloy by powder metallurgy method was developed to produce a bioimplant material with a low modulus of elasticity. Microstructure characterization and phase identification were carried out to support the development of bone implant material research. The alloys were synthesized with the elemental composition of 16 Cr (wt%) that was added with Al in variations of 3, 6, and 10 (wt%). The synthesis was carried out by an exceptional combination of mixing and mechanical milling, cold compacting and consolidating with a special method using the APS (Arc Plasma Sintering) apparatus. Microstructure characterization and phase identification were analyzed by SEM-EDS and XRD tests. The microstructure showed relatively homogeneous fine grain with small porosity of around 80 %. Refinement of the XRD peak pattern revealed the formation of the Fe-Cr main phase followed by the Fe-Al phase with Al as the solid solution. The hardness test showed a high hardness level with a maximum for Fe-16Cr-6Al (wt%) of around 160 VHN (Vickers Hardness Number). The quantity of Fe-Cr phase and the composition of Al influenced the hardness of the alloy.

“…The schematic diagram of APS is shown in Figure 1. In previous studies, APS was able to sinter some magnesium-based alloy (Mg-Zn), oxides dispersed alloy (Fe-25Cr-Y 2 O 3 ), and also bulk titanium alloy (Ti6Al4V) in a relatively short time (less than 1 hour) [29][30][31] .…”

Porous titanium is proposed to be an effective orthopedic implant with a lower elastic modulus and supports osseointegration during implantation. To produce porous titanium, powder metallurgy (PM) assisted with a space-holder is used in this study. Pure titanium is used as the starting material, and salt (NaCl) is used as the space-holder. Argon-atmospheric sintering and arc plasma sintering (APS) methods are applied for the sintering process. NaCl content was varied from 0-40 wt%. The temperature sintering was at 1100 °C for the argon-atmospheric sintering, and the current process was at 75 A for the APS. The formation of pores, total porosity, pore distribution, phase formation, and mechanical properties were examined by the optical microscope, scanning electron microscope (SEM), X-ray diffraction (XRD), and compression testing. Titanium with the addition of 20 wt% of NaCl is shown to be a potential biomaterial for the orthopedic implant, having a porosity of 38-39%, the elastic modulus of 3.2-5 GPa, and the yield strength of 141-150 MPa (argon-atmospheric sintering and APS) which shown to be similar to the properties of cortical bone.
