Dynamic impact analysis of AISI 316L coated with Al-5Mg in air and seawater

Abstract

In this study, the impact wear behaviour of Al-5Mg, used as a corrosion protective coating was investigated in seawater and air environments. Tests were conducted for up to 10(5) cycles on the plane surface of Al-5Mg coated AISI 316L samples. Wear at the frequency of 2.5 Hz kept the coating thickness at a reliable level. However, the wear that occurred under the frequency of 5Hz reached the substrate surface. In the experiments conducted in seawater, smoother wear scars were formed compared to those in the air environment tests. The coating particles separated by the wear effect were compressed by the impactor on the wear surface with repetitive impacts, causing delamination. Friction oxidation was formed on wear scars. The hydrodynamic effect of seawater reduced the delamination by removing the separated coating particles from the surface. Thus, in seawater, 70% more wear occurred compared to in the air environment.
