Paper Abstract

Wear and corrosion resistant multi-functional Cr3Si-Cr2Ni3Si composite coatings were fabricated on substrate of an austenitic stainless steel 1Cr18Ni9Ti by laser cladding using different Cr-Si-Ni alloy powders. Microstructure, metallic dry sliding wear and electrochemical corrosion behaviors of the metal suicide matrix composite coatings were investigated as a function of the Cr3Si volume fraction. The laser clad composite coatings have a rapidly solidified microstructure consisting of Cr3Si primary dendrites and the interdendritic Cr2Ni3Si ternary metal silicide. The volume fraction of primary Cr3Si dendrites was shown to have a remarkable influence on wear and corrosion resistance of the laser clad composite coatings. The higher the volume fraction of Cr3Si, the higher he wear and corrosion resistance of the coatings.
