To improve the durability of the PFM crowns, it is important that porcelain strongly bond to coping surface mechanically and chemically. In the present study, we evaluated the strength of mechanical retention of the porcelain to the 14K gold alloy with a sponge-like surface structure. The cross section of porcelain-alloy interface was observed using SEM and EPMA. Debond/Crack-initial strength and colour of fired specimen were measured. The establishment of strong and durable bonding interface can be possible with forming the sponge-like structure on the gold alloy surface.
