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.

本研究的目的是研究使用实验开发的具有直流电源的设备（初始电压：400 V，电流密度：0.2 mA/mm^2）通过冷等离子体处理（CP处理）对商业纯钛和牙科用Ag-Pd合金进行表面处理的有效性。考察了CP处理对树脂基粘结剂粘结性能的影响以及CP处理对金属底漆的吸附情况。CP处理显著提高了牙用金属的拉伸粘结强度。钛合金CP处理时间为3 min，银钯合金CP处理时间为10 min，有利于键合。扫描电镜观察显示，CP处理没有改变钛的表面织构。然而，经过CP处理后的Ag-Pd合金的表面显示出明显的粗糙表面的等离子体蚀刻效应。通过CP处理回收的人唾液污染的钛板。FT-IR表明CP处理增强了金属底漆与钛的反应，以去除污染物。
