In order to better understand the tribological behavior of magnesium composites for use in biomedical applications, this study focuses on the wear properties of Mg-1%Sn-x%HAp (x = 2, 5, 7 wt.%) composites under dry sliding conditions. The composites under investigation consist of magnesium alloyed with 1% tin and different quantities (2, 5, and 7% by weight) of hydroxyapatite powder (HAp). The composites were synthesized using a high-energy planetary ball mill, and then subjected to compression and sintering. Wear testing was conducted using a pin-on-disc apparatus following the ASTM G99 standards. The study employed the Taguchi design of experiments to evaluate the influence of applied stress, sliding speed, and hydroxyapatite (HAp) reinforcing % on wear rate. The analysis of variance (ANOVA) reveals that the percentage of HAp and the applied load are significant parameters that greatly influence wear behavior. More precisely, the HAp percentage accounts for 52.94% of the fluctuation, whereas the applied load accounts for 40.92%. The lowest wear rate 0.16708 μm/s was observed with the combination of 10N load at 300 rpm with 7% of HAp powder and the highest wear rate 0.41360 μm/s was observed at 20N load, 300 rpm and 5% HAp. The results indicate that the level of wear resistance was positively correlated with the amount of HAp present, whereas the level of wear is positively correlated with greater loads. The results provide valuable insights into the optimal optimization of magnesium-based composites for durable biomedical implants.
