主　　题：WC Co Microstructure and Properties of WC-Co/NiCrBSi Brazing Coating 

摘      要：Through rolling technology, a flexible metal cloth consisting of metal powder (NiCrBSi powder or WC-Co powder) and organism in a certain ratio were made, which could be used as brazing coating raw materials. WC-Co/NiCrBSi wear coating was fabricated through high temperature vacuum brazing after the flexible metal clothes were assembled on 42CrMo steel surface. The tensile strengths of coating self and coating/matrix approached to 100 similar to 140 MPa and 300 similar to 360 MPa, respectively, at different brazing parameters. Effect of Co on the wear property of the coating was analyzed. The abrasive wear property of WC-Co/NiCrBSi brazing coating is better than WC-17Co/NiCrBSi flame overlaying and CoCrW overlaying.
