Abstract

Two groups of cobalt-chrome-wolfram alloys, Co-Cr-W-Si and Co-Cr-W-Mo-Si, were selected for additive manufacturing. One of these samples was subjected to heat treatment after production under the same conditions. Thus, it is aimed to investigate the effects of heat treatment and molybdenum doping on the corrosion behaviour of cobalt-chrome alloys. The corrosion behaviour of the samples was investigated by using an electrochemical corrosion technique. Ringer's solution was used for the aqueous environment of the electrochemical corrosion technique.
