Low-fusing　dental　porcelain　was　fused　on　titanium　surface.　The　adhesion　between　the　titanium　and　porcelain　was　evaluated　by　three-point　flexure　test.　It　was　shown　that　the　failure　of　the　titanium-porcelain　predominantly　occurred　at　the　alloy-oxide　interface.　Rutile　phase　was　present　on　the　interface　debonding　from　porcelain.　The　influence　of　corrosion　on　bonding　strength　was　also　investigated.　The　results　suggested　that,　after　being　immersed　in　artificial　saliva　with　pH　of　2.7,　5.4　and　7.0.　no　decreasing　of　the　bonding　strength　of　Ti-porcelain　occurred.
