Article Preview

Wear and corrosion resistant multi-phase transition metal silicides coatings including W2Ni3Si/W5Si3, Ti5Si3/NiTi2, Ti2Ni3Si/NiTi, etc, were developed and fabricated by laser cladding process. Tribological properties were evaluated under dry sliding and reciprocating fretting wear test conditions and the responding wear mechanisms were discussed as functions of microstructure constitutions and test conditions. High temperature oxidation resistance of the coatings was investigated. The coatings exhibited excellent combination of room and high temperature metallic sliding wear resistance, fretting propertiy, metallic tribological compatibility, good oxidation resistance and abnormal wear-load dependence. Applications of the coatings were prospected for the aerospace, petrochemical and energy-processing industries.
