Abstract采用真空熔覆技术在45#钢表面制备了不同Co含量的Ni-Co基合金熔覆层及Ni-Co+WC、Ni-Co+WC+Graphite复合熔覆层,研究了涂层在3.5% NaCl溶液中的电化学行为。结果表明,在ZG45表面制备的Ni-Co基合金熔覆层的自腐蚀电位随Co含量的增加而升高,其自腐蚀电位相比ZG45至少提高了4.98%,腐蚀电流则降低了74.93%。在Ni-Co基合金熔覆层中添加WC和石墨(G)后其自腐蚀电位提高:同时添加WC和G时的自腐蚀电位相比只添加WC时提高了32.39%,腐蚀电流则降低了19.37%;且同时添加WC和G试样的自腐蚀电位比Ni-40%Co提高33.86%,耐腐蚀性能相比Ni-Co基合金得到了增强和改善。另外,在同时添加WC和G的试样的极化曲线上出现了钝化区,且其钝化区腐蚀电位宽度大于只添加WC的试样,说明前者的耐腐蚀性优于后者。
