Abstract
The corrosion-wear behaviour of 304 stainless steel in various NaCl solutions with various loading conditions was qualitatively studied. A ‘dynamic corrosion-wear cell’ was designed. This apparatus was pin-on-disk type and constructed to meet the purpose of this work. In the process of experiments, potentiostatic and potentiodynamic methods were utilized to determine the effects of the environments and rubbing motion under load on the wear and corrosion of 304 stainless steel. Optical microscopy and surface roughness measurements were conducted on the samples. It was observed, firstly, that chloride ions enhance the corrosion-wear. Secondly, increasing the loadings and quantity of chloride ions reduces the polarization resistances. It was stated that the higher loading created a larger metal surface, thus leading to the formation of more active regions.
