Abstract
The effects of titanium ion implantation on the surface chemical composition, roughness, and microstructure, as well as corrosion mechanism of 316L stainless steel in acid solution are investigated. The bare SS316L has a polycrystalline structure containing second-phase inclusions. These defects are prone to pitting corrosion and intergranular corrosion as observed by SEM. After Ti ion implantation, the outer surface is completely amorphized and homogenized and the region underneath is partly disordered. Consequently, localized corrosion is avoided and the sample undergoes general corrosion. With increasing ion implantation voltages, the surface roughness increases and the corrosion resistance decreases due to more extensive radiation damage as result of energetic ion bombardment. © 2011 Elsevier B.V.
