However, for strengthening the water durability of the adhesive interface, the oxidation of the alloy surface is indispensable. A new oxidation method using ion-sputtering was developed, and the effectiveness of this surface treatment on two dental alloys-a type IV gold alloy and Ni-Cr-Be alloy-was investigated. As an endurance test, thermocycling for a maximum of 100, 000 cycles was adopted, and the tensile adhesive bond strength was then measured. Ion-coating the surface of the alloys resulted in strong bonds with adhesive resins, and after 100, 000 thermocycles, a bond strength of above 20 MPa was maintained.
