Interfacial Characterization of Porcelain Veneered on the Pure Titanium under Vacuum Firing

MATERIALS TRANSACTIONS, 2004
The interfacial characteristics between porcelain coating and titanium under vacuum firing at 800°C have not been well documented. The cross-sectional variations in microstructures and compositions at the porcelain/Ti interface were investigated with a SEM and an EPMA equipped with WDS.
