Previous study found that ion coating treatment with Cu target demanded 10 minutes of treatment to achieve the durable adhesion witla 4-META resin. For clinical application, it's indispensable to shorten the treatment period. Sn and Cu-Sn target were examinedin this study. 4 minutes of treatment with Sn target showed high bond strength of adhesion. However, the excess of treatment time over 8 minutes caused the remarkable decrease of adhesion durability against thermal cycling. In clinical situation, many of the prosthesis possess the wings of complex shape and it's difficult to attain the uniform coating by only once treatment. However, the repetition of treatment with Sn target is undesirable because of the decrease of adhesion durability. avorable result was shown by 4 minutes of treatment with Cu-Sn target and even by 30 minutes of treatment, same result was attained. With this ion treated specimens of Au-Ag-Pd alloy sandblasted, the adhesive bond strengthof above 200kgf/cm^2 was maintained after 100,000 thermocycles.
