摘要：
Fe-based WC composite coatings are prepared on the surface of A3 steel by laser induction hybrid rapid cladding(LIHRC). Microstructure and microhardness characteristics of the composite coatings are investigated. The results show that WC particles are almost dissolved completely and interact with Fe-based alloy, so that M6C are precipitated in the Fe-based interdendrite matrix phase. The reason why the microhardness of Fe-based WC composite coating is relatively low is that WC particles are dissolved completely and the retained austenite is precipitated during laser induction hybrid rapid cladding.
