In　this　work,　TiB2-Ni　cermet　coating　was　deposited　by　atmospheric　plasma　spraying　using　two　kinds　of　feedstock,　namely　agglomerated　powder　and　clad　powder.　The　microstructure　and　the　phase　composition　of　the　powder,　as　well　as　the　sprayed　coating　were　analyzed.　The　microhardness　(Hv)　and　the　fracture　toughness　(K-IC)　of　the　coating　were　also　evaluated.　The　results　showed　that　the　phenomenon　of　TiB2　particle＇s　rebounding　in　deposition　and　the　dissolution　of　TiB2　were　closely　related　to　the　feedstocks＇　characteristic,　e.g.　TiB2　particle　size,　binder　content　and　its　morphology,　which　played　an　important　role　on　the　coating　microstructure　and　its　mechanical　properties.　The　tribological　performance　of　the　coating　was　also　assessed　using　a　linear　reciprocating　friction　tester　with　GCr15　counterpart　The　coating　deposited　from　agglomerated　and　sintered　TiB2-40　wt.%　Ni　powder　presented　better　tribological　properties,　i.e.　low　friction　coefficient　and　wear　rate.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
