Corrosion stability of metallic materials used in dentistry is a major concern; identification of materials combining high stability and good performance is needed. The corrosion resistance of representative nonprecious metal alloys frequently used in dentistry in contact with artificial saliva solution with various added substances encountered in foodstuffs and in materials used in dentistry, possibly influencing the corrosion has been studied in vitro with electrochemical impedance measurements. Values of obtained corrosion resistances are interpreted in terms of conceivable effects of the additives on the rate of corrosion; they are also compared with previous results obtained with these alloys and additives using breakthrough electrode potentials obtained from slow scan cyclic voltammetry reported before.

常见唾液添加剂存在下牙科非贵金属合金的腐蚀

牙科中使用的金属材料的腐蚀稳定性是一个主要问题；需要鉴定兼具高稳定性和良好性能的材料。已通过电化学阻抗测量在体外研究了牙科中经常使用的代表性非贵金属合金的耐腐蚀性，这些合金与人工唾液溶液接触，其中添加了食品和牙科材料中遇到的各种添加物质，可能影响腐蚀。根据添加剂对腐蚀速率的可能影响来解释获得的耐腐蚀性值；他们还与之前报道的使用从慢扫描循环伏安法获得的突破电极电位使用这些合金和添加剂获得的先前结果进行了比较。
