Study on Thermal-Shock-Resistance of the Composite Coating of 20 Steel Substrate by Hot Dip Aluminum and Micro-Arc Oxidation

Abstract:

By combined process of hot dip aluminum and micro–arc oxidation, a multilayer composite coating was obtained on the surface of 20 steel plates. The micro-hardness, morphology, residual stress and thermal-shocking performance of the coating were investigated by HVS-1000 micro-hardness instrument, SEM, X-350 stress instrument and etc. The results showed that the micro-hardness of the coating appeared hard-soft-hard from surface to inner, the effective thermal-shock times of the coating was 130, its residual stress of the coating was 181.7 MPa after hot shock 80 times.
