Abstract
The fabrication of a rapidly solidified γ/Cr3Si metal silicide composite coating by laser cladding was discussed. The operation was performed on a substrate of austenitic stainless steel using Cr-Si-Ni elemental powder blends. The coating was metallurgically bonded to the substrate and had a rapidly solidified homogenous microstructure. Metal silicide composite coating was found to have excellent high-temperature wear resistance due to the presence of a large amount of hard, wear and oxidation resistant primary Cr3Si dendrites.
