摘要

•The corrosion behavior of SLM and Cast Co-Cr-Mo-W alloy was investigated by electrochemical techniques.•The lower content of precipitates generates a more homogenous structure and improve the corrosion resistance.•The large precipitates act as effective micro-cathode resulting in pitting corrosion and high corrosion rate.
