Abstract
The property of corrosion resistance for C+ + W+ dual-implanted H13 steel w as studied using multi-sweep cyclic voltammetry. The phase formation condit ions for corrosion resistance and its effects were researched. The super-sa turation solid station solution of W+ and C+ atoms was formed in tungsten p lus carbon dual-implanted steel. Nanometer size precipitates consisting of the phases of Fe2W, FeW, WC, Fe5C3 and Fe7C3 were formed in the dual-implan ted layer. The passivation layer consisted of the nanometer phases. The cor rosion resistance of the dual implanted layer is better than that of single implantation. The corrosion resistance of the dual implantation was enhanc ed following increase of ion dose. When the W+ ion dose was 6 x 10(17)/cm(2 ) in the dual implantation, J(p) of the dual implanted sample is 17-33 time s less than that of J(p) in H13 steel. (C) 2000 Elsevier Science S.A.
