The　work　aims　to　prepare　metallic　coatings　on　Cf/SiC　composite　substrate　by　plasma　spraying　(APS).　Based　on　the　analysis　of　coating　characteristics　and　interfacial　bonding　of　the　plasma　sprayed　Mo,　NiCrBSi　and　in-house　Ti70Ni20Cu10　composite　powder,　a　Mo-10wt.%Ti　composite　coating　was　prepared.　The　composite　powder　subject　to　spraying　was　made　by　cladding　large　particle　Mo　powder　with　small　TiH2　powder　with　a　low-energy　ball　milling　method.　The　substrate　temperature　was　preheated　to　700　during　spraying,　and　the　spraying　was　conducted　under　an　argon　atmosphere.　The　sprayed　Mo-10Ti　coating　presented　a　dense　and　uniform　microstructure,　with　low　porosity　and　without　obvious　cracks.　The　coating　was　well　bonded　to　the　substrate　without　any　peeling.　The　bonding　strength　of　the　coating　exceeded　6.3　MPa,　and　fracture　occurred　at　substrate.　The　thermal　expansion　coefficient　and　the　wettability　of　the　material　are　the　key　factors　affecting　the　adhesion　of　plasma　sprayed　metallic　coating　on　the　Cf/SiC　composite　substrate.　The　designed　Mo-Ti　composite　coating　takes　both　two　issues　into　account.　©　2019,　Chongqing　Wujiu　Periodicals　Press.　All　rights　reserved.
