Abstract
The property of corrosion resistance for C++W+ dual-implanted H13 steel was studied using multi-sweep cyclic voltammetry. The phase formation conditions for corrosion resistance and its effects were researched. The super-saturation solid station solution of W+ and C+ atoms was formed in tungsten plus carbon dual-implanted steel. Nanometer size precipitates consisting of the phases of Fe2W, FeW, WC, Fe5C3 and Fe7C3 were formed in the dual-implanted layer. The passivation layer consisted of the nanometer phases. The corrosion resistance of the dual implanted layer is better than that of single implantation. The corrosion resistance of the dual implantation was enhanced following increase of ion dose. When the W+ ion dose was 6×1017/cm2 in the dual implantation, Jp of the dual implanted sample is 17–33 times less than that of Jp in H13 steel.
