Dental alloys coated with (Ti,Nb)ON using the ion are PVD technique exhibit galvanic corrosion current densities of considerably less than Jg = 1 microA/cm2. These measurements were taken on plane surfaces. The results show no signs of local corrosion, which might impair the long-term intraoral stability of dental constructions or the health of the patients. Irrespective of the dental alloys used, the coatings exhibit pores extending down to the alloy. The alloy thus wetted on the one hand, and the coated areas on the other, act as galvanic elements with high source resistances and very low short circuit currents. It may therefore be concluded that the coating will effectively reduce allergic reactions to the components of the dental alloys.
采用离子束物理气相沉积（PVD）技术涂覆（Ti，Nb）ON的牙科合金，其电偶腐蚀电流密度远低于Jg = 1微安/平方厘米。这些测量是在平面上进行的。结果表明没有局部腐蚀的迹象，而局部腐蚀可能会损害牙科修复体在口腔内的长期稳定性或患者的健康。无论使用何种牙科合金，涂层都存在延伸至合金的孔隙。一方面被润湿的合金，另一方面被涂覆的区域，作为具有高源电阻和极低短路电流的电偶元件。因此可以得出结论，该涂层将有效减少对牙科合金成分的过敏反应。
