Influence of Molybdenum on Tribo-Corrosion Behavior of 316L Stainless Steel in Artificial Saliva

Abstract

The influence of molybdenum on the tribo-corrosion behavior of 316L stainless steel in artificial saliva was investigated using potentiodynamic polarization curve, electrochemical impedance spectroscopy and sliding wear testing. The results showed that the passive capability of 316L stainless steel in artificial saliva was enhanced with increasing Mo. The anti-corrosion property of the passive film on 316L stainless steel was improved with increasing Mo via increasing transfer resistance of the passive film. Sliding wear testing results showed that the friction coefficient of 316L stainless steel in artificial saliva decreased with the increased Mo.
