The　SnO(x)　film　was　deposited　on　titanium　by　sol-gel　dipping　process.　After　drying　at　80　degrees　C　for　5　h,　the　films　were　treated　for　10　min　at　different　temperature.　A　thin　and　coherent　SnO(x)　film　with　small　spherical　pores　obtained　at　300　degrees　C　served　as　an　effective　oxygen　diffusion　barrier　and　improved　titanium-porcelain　adhesion.　The　SnO(x)　film　changed　the　fracture　mode　of　the　titanium-porcelain　system　and　improved　the　mechanical　and　chemical　bonding　between　porcelain　and　titanium,　resulted　in　the　increased　bonding　strength　of　titanium-porcelain.
