Inductively coupled argon plasma spectroscopic analysis was used to quantify titanium, aluminum, and vanadium corrosion products released by superficial layers of identically shaped commercially pure titanium and Ti-6A1-4V alloy dental implants. Halves of each of two originally sterile groups were analyzed directly from the manufacturer's packaging and the other halves received glow-discharge treatment prior to their corrosion assay. The implants were incubated in pH 3 modified saline solution and were analyzed after 2- and 12-week corrosion periods. Implants treated with glow discharge showed statistically significant reduction in the amounts of corrosion products released, apparently as a result of glow-discharge-produced surface oxides of greater passivity than originally present.
采用电感耦合氩等离子体光谱分析法定量分析形状相同的商业纯钛和Ti-6Al-4V合金牙科植入物表层释放的钛、铝和钒腐蚀产物。最初无菌的两组中的每组一半直接从制造商包装中取出进行分析，另一半在进行腐蚀试验前接受辉光放电处理。将植入物在pH值为3的改良盐溶液中孵育，并在2周和12周的腐蚀期后进行分析。经辉光放电处理的植入物释放的腐蚀产物量在统计学上显著减少，这显然是由于辉光放电产生的表面氧化物比原来的更具钝性。
