Effect of SnO Coatings on the Bond Strength between Titanium and Porcelain
The aim of this investigation is to study the effect of SnO coatings on the bond strength between titanium and porcelain.The coatings were produced by sol-gel method and heat-treatment at 300℃.Once the coatings have been formed on the titanium substrates,self-made porcelain was fused.The specimens with pre-oxidation before porcelain fused were set as control group.It was shown SnO gel formed completely at 300℃ and was composed by SnO and SnO2 in the form of a uniform film.The bond strength between titanium and porcelain of the specimens with SnO coatings was greater than those in control group statistically,which might prove that the coatings reduced the oxidation of titanium surface in the porcelain fusing progress.EDS result showed almost all fractures between titanium and porcelain occurred atthe oxide layer.Si and Sn might attend the reaction at interface.It was concluded that the SnO coatings produced in this study can improved the titanium-porcelain bond strength.
