[The bonding strength between plat castable ceramics and mild fusing alloy].
Plat castable ceramics (PCC) was bonded to SDA-I mild fusing alloy using three bonding agents, and the tensile bond strengths were tested respectively in order to select the best bonding agent and the best way of surface treatment. The results obtained with scanning electron microscope and X-ray energy spectrum showed that the bonding behavior of TF agent was the best one. The greatest tensille bond strength (24.37 MPa) was obtained with TF agent when the surface of PCC was etched by hydrofluoric acid and the alloy was painted with KH-570. Remarkable tensile bond strengths were noted in the group where EM agent was used with PCC etched by hydrofluoric acid and alloy treated with sandblasting (15.20 MPa), and in the group where Porcelite dual cure cement was applied with PCC painted by KH-570 and alloy treated with sandblasting (15.25 MPa).
