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 tempera ture vacuum brazing after the flexible metal clothes were assembled on 42CrMo steel surface.The tensile strengths of coating self and coating/matrix approached to 100~140 MPa and 300~360 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
