Effect of cold work on erosion-corrosion of 304 stainless steel

摘要

Slurry and single particle impingement experiments were performed to study the effects of cold work on erosion-corrosion properties of 304 stainless steel. The specific energies of crater formation on samples were calculated and it was shown that these energies are constant for samples with specific amount of cold work at various impact velocities. The role of frictional force and its effective path of action were investigated during the depassivation process. It was found that the coefficient of friction between the particle and the surface remains invariant regardless of the amount of cold work that is applied to the sample.
