Investigation Basic Properties of Custom Designed Controlled Porous Implants Produced by P/M Method for Biomedical Applications

This study investigates the production of implant-like porous pure titanium materials for biomedical applications, produced by powder metallurgy (T/M). The material consists of a solid titanium core and a porous titanium outer layer designed to enhance bone conformability and strength. Magnesium powder (50 µm) was used in proportions of 10, 20 and 30 wt% to create the porous structure. The samples were sintered in argon atmosphere at 1000°C, 1100°C and 1200°C for different times (60, 90 and 120 minutes) and Magnesium was removed. The experimental work was carried out by tensile stripping test in a tensile testing machine. The effects of sintering temperature, time and grain size were analyzed by Taguchi method. ANOVA and Signal-to-Noise (S/N) ratio analyses were applied to evaluate joint quality and optimize strength. The findings contribute to the understanding of cost-effective design parameters for high-strength porous titanium implants, highlighting the influence of processing conditions on mechanical performance.
