The studies were focused on the corrosion stability of dental alloys (containing NiCr and stainless steel), for a possible release of Nickel (Ni). The investigations were carried out in artificial saliva at 37 degrees C. The potential range, where Ni dissolution may occur, was determined by transient measurements. It has been established, that: 1. Under in vivo conditions the probability of the pitting corrosion is very low. 2. The Ni release takes place on the temporarily damaged, locally activated parts of the surfaces.
这些研究聚焦于牙科合金（含镍铬合金和不锈钢）的腐蚀稳定性，以探究镍（Ni）的可能释放情况。研究在37摄氏度的人工唾液中进行。通过瞬态测量确定了可能发生镍溶解的电位范围。现已确定：1. 在体内条件下，点蚀的可能性非常低。2. 镍的释放发生在表面暂时受损、局部活化的部位。
