Abstract
Erosion behaviors of AISI 430 and 304 stainless steels, ARC-TEN weathering steel, brass, and 6063 aluminum alloy were experimentally investigated using a sandblasting type test rig and silicon carbide erodent particles. Surface morphologies of eroded specimens were examined using scanning electron microscopy. The volume loss was measured for the evaluation of erosion rates. This paper stresses the relationship between erosion rate and surface hardness (before and after erosion). It was found that the erosion rate is proportional to (Hv)(-n), where Hv is the microhardness number after erosion testing, and the exponent n is 1.4 or 3, depending on conditions.
