Abstract:
objective: To study the metal ceramic bond of reused surplus alloy of a precious metal ceramic alloy. Methods: The samples in control group for reused surplus alloy were treated by only remelting without adding any fresh alloy up to four generations, those in the test group by adding one third fresh alloy in each generation and up to four generations. Metal ceramic bond strength of the samples was surveied by pull shear test. Results: In control group, the pull shear bond strength (MPa) from generation Ⅰto Ⅳcastings was 47.53?2.02, 33.23?2.03, 25.08?1.88 and 14.61?1.56 respectively( P
