Abstract

A novel rapidly solidified Cr₃Si/Cr₂Ni₃Si composite coating is fabricated on the substrate of 0.20% C low carbon steel by laser cladding using Cr-Si-Ni elemental powder blends. The laser clad coating has a homogeneous microstructure consisting of Cr₃Si primary dendrites uniformly distributed in the Cr₂Ni₃Si complex silicide matrix and is metallurgically bonded to the substrate. The laser clad Cr₃Si reinforced Cr₂Ni₃Si silicide matrix composite coating has good wear resistance under the dry sliding wear test condition and the pin-on-disk abrasive wear test condition.
