The purpose of this sturdy was to investigate the effectiveness of surface treatment to commercial pure titanium and dental Ag-Pd alloy applied by cold plasma treatment (CP treatment) using the experimentally developed equipment having a DC power supply (Initial voltage: 400V, Current density: 0.2mA/mm^2). Treatment effect to bonding characteristics of resin-based luting cement and adsorption situation of metal primer by CP treatment were also examined. Tensile bond strength of dental metals was increased by CP treatment significantly. CP treatment for three minutes to titanium, and that for ten minutes to Ag-Pd alloy were was suitable for bonding. SEM observation appeared CP treatment did not change the surface texture of titanium. However, the surface of Ag-Pd alloy after CP treatment showed significant rough surface by plasma-etching effect. Titanium plates contaminated with human saliva recovered by CP treatment. FT-IR indicated CP treatment enhanced the reaction of the metal primer to titanium in order to remove the contamination.

这种坚固的目的是使用具有直流电源的实验开发的设备（初始电压：400V，电流密度：0.2mA/mm^2）研究表面处理对商业纯钛和牙科AG-PD合金的有效性。还检查了通过CP治疗的基于树脂基水泥和金属底漆吸附情况的粘合特性的治疗效果。 CP处理可显着提高牙齿金属的拉伸键强度。 CP治疗三分钟到钛，持续十分钟到Ag-PD合金非常适合粘合。 SEM观察似乎CP处理并没有改变钛的表面质地。但是，CP处理后AG-PD合金的表面通过血浆蚀刻作用显示出明显的粗糙表面。通过CP治疗回收的人类唾液污染的钛板。 FT-IR表示CP处理增强了金属引物对钛的反应，以消除污染。
