The　metal　nickel　(Ni)　on　the　surface　of　alumina　(Al2O3)　ceramic　was　deposited　with　NiCl2powder　as　a　raw　material　by　a　chemical　vapor　deposition　technique　and　subsequent　H2reduction　treatment.　The　phase　composition,　adhesion　between　the　coating　and　Al2O3ceramics　and　wetting　behavior　between　the　coating　and　molten　copper　were　investigated.　The　resurts　indicate　that　main　component　is　Ni　in　the　prepared　coating,　the　Ni　coating　with　the　thickness　of　40　μm　is　uniform　and　dense.　The　effective　binding　between　the　Ni　coating　and　Al2O3ceramic　occurs.　The　contact　angle　between　Ni-coated　Al2O3ceramic　and　molten　copper　is　30.15°　measured　by　a　sessile　drop　test,　showing　the　improvement　of　the　wettability　between　ceramic　and　metal　due　to　the　coating.
