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.
