摘要：

The　nanostructured　WC-CoCr　coating　was　fabricated　by　the　high　velocity　oxy-fuel　(HVOF)　thermal　spraying　using　a　new　type　of　WC-CoCr　powder,　in　which　the　Co-Cr　exists　in　a　form　of　metallic　compound.　The　Co-Cr　alloy　powder　was　prepared　by　the　induction　melting　and　subsequent　mechanical　milling.　Detailed　characterizations　were　carried　out　on　the　phase　constitution　and　microstructure　of　the　Co-Cr　powder　and　the　cermet　coating,　as　well　as　the　mechanical　properties　and　corrosion　resistance　of　the　coating.　The　results　show　that　the　nanostructured　WC-CoCr　coating　has　greatly　improved　corrosion　resistance　as　compared　with　the　conventional　WC-Co-Cr　coating　where　Cr　exists　as　single　metal.
