Corrosion Resistance of the Implant Materials Contimet 35, Memory, and Vitallium in Artificial Physiological Fluids

The linear polarization method has been used to demonstrate the influence of different electrolytes on the corrosion behavior of Ti, Ni-Ti, and Co-Cr-Mo. Results revealed minimal corrosion tendency for Ti; Co Cr-Mo, and especially Ni-Ti, showed rapid breakdown of passivity with increasing chloride concentrations in unbuffered solutions and little differences in buffered solutions.
