| Popis: | AISI 316L is one kind of implant materials due to its excellent mechanical properties and corrosion resistance. However, some of their mechanical and surface properties must be improved to a higher level of cobalt-based alloys and titanium properties. Shot peening is a surface treatment that improves properties on material surface. In this research, the effects of shot peening duration (0, 2, 4, 10, 20 and 30 min) on surface hardness, roughness, wettability, and corrosion in 0,9 % sodium chloride were investigated and discussed. According to the experimental results, it was found that shot peening increases both surface roughness and surface hardness compared to untreated sample. Furthermore, shot peening can reduce contact angle and corrosion rate after 2 minutes. |
