[Study of low-fusing porcelain fused to Ti-75 alloy].
OBJECTIVE
To study the feasibility of low-fusing porcelain fused to Ti-75 alloy.


METHODS
The bond strength and interfacial state of porcelain-titanium were observed by EPM analysis and shear test.


RESULTS
The results showed that the shear bond strength of low-fusing porcelain fused with Ti-75 alloy and the conventional porcelain fused to base metal alloy (NC-VMK68) respectively were 47.38 +/- 7.95 MPa and 48.50 +/- 7.60 MPa. There were no significant difference in the shear bond strength between the two results (P > 0.05). The analysis of electron microprobe showed that there was no crack in the interface, the low-fusing porcelain permeated Ti-75 alloy fairly, and titanium diffused from Ti-75 alloy to porcelain, and silicon, stannum diffused from porcelain to Ti-75 alloy.


CONCLUSIONS
Ti-75 alloy can be regarded as a suitable alloy for low-fusing porcelain.
