The study investigated the wear behavior of 316L stainless steels produced with mechanical alloying in simulated body fluid. Results showed a decrease in powder size as milling time increased, with highest hardness and lowest weight loss achieved in specimens milled for 60 minutes. Surface roughness varied among specimens milled for different times.
In the present study, the wear behavior of 316L stainless steels (SS) produced with mechanical alloying (MA) method was investigated in simulated body fluid. Alloys produced in different MA times were sintered for 2 h at 1300 degrees C temperature. Specimens prepared with standard metallographic procedures after sintering, scanning electron microscopy, X-ray diffraction, powder size analyses, hardness, and density measurements were performed. Wear tests were carried out in pin-on-disc type wear device, Kokubo simulated body fluid and body temperature environment (in vitro). Surface roughness was measured before and after the wear test under 40 N at four different sliding distances with 1 ms(-1) sliding speed. Results showed that the powder size decreased as the milling time increased and the lowest powder size was measured for the powder milled for 120 min. The highest hardness and lowest weight loss were achieved in specimens milled for 60 min, while the highest average surface roughness was achieved in specimens milled for 30 min.
