Abstract: As a typical boride ceramics，WC ceramics have become a researched hot point because of its high melting point，good chemical stability，high hardness and good resistance to abrasion． The WC granule is in－situ synthesized during the reaction of the alloy powders employing the TIG powder surfacing． The microstructure and morphology of the tungsten carbide coating is observed and analyzed． The abrasive wear performance of the coating is also studied．
Key words: WC; Coating; Abrasive wear
