摘要：

Wear resistant Cr-Ni-Si metal silicide alloy with a microstructure primarily consisting of ternary metal silicide Cr13Ni5Si2 primary dendrites was fabricated by the laser melting (Lasmelt) process using Cr-Ni-Si elemental powder blends as the precursor materials. Microstructure of the alloy was characterized by optical microscopy, scanning electron microscopy, X-ray diffraction and energy dispersive X-ray analysis. Wear resistance of the Cr13Ni5Si2 alloy was evaluated Under dry sliding wear test conditions at room temperature. Results indicate that the Cr13Ni5Si2-based metal silicide alloy has excellent wear resistance under dry sliding wear test conditions. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd.
