Previous study found that ion coating treatment with Cu target demanded 10 minutes of treatment to achieve the durable adhesion with 4-META resin. For clinical application, it's indispensable to shorten the treatment period. Sn and Cu-Sn target were examined in 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. Favorable 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 strength of above 200 kgf/cm2 was maintained after 100,000 thermocycles.
先前的研究发现，使用铜靶进行离子涂层处理需要10分钟才能与4-META树脂实现持久的粘结。对于临床应用而言，缩短处理时间是必不可少的。本研究对锡靶和铜锡靶进行了检测。用锡靶处理4分钟显示出较高的粘结强度。然而，处理时间超过8分钟会导致热循环后粘结耐久性显著下降。在临床情况下，许多修复体具有复杂形状的翼部，仅通过一次处理很难获得均匀的涂层。然而，由于粘结耐久性下降，重复使用锡靶进行处理是不可取的。用铜锡靶处理4分钟显示出良好的效果，即使处理30分钟也能获得相同的结果。对经过这种离子处理的金-银-钯合金喷砂试样，在100,000次热循环后仍保持高于200 kgf/cm2的粘结强度。
