摘　　要：为了提高钢丝的耐腐蚀性能,使用连续涂覆工艺制备一系列锆基非晶合金(Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10)Be_(22.5))_(100-x)Nb_x(x=0,3,5,8,at%)涂覆Q195钢丝。相分析结果表明,涂层主要由非晶基体和一些金属间化合物组成;阳极极化实验发现所有非晶涂覆钢丝表现钝化行为,具有高的点蚀破钝电位和低的腐蚀电流。随着非晶涂层中铌含量增加,非晶涂覆钢丝的钝化区宽度增加,点蚀破钝电位升高。电子能谱分析发现,非晶涂覆钢丝抗点蚀性能提升可能与金属铌元素容易钝化,形成稳定钝化膜,同时能够稳定锆、钛,降低相分离有关。To improve the corrosion resistance of steel wires, a uniform thin layer of bulk metallic glass alloy with different compositions of（Zr41.2Ti13.8Cu12.5Ni10Be22.5）100-xNbx（x=0, 3, 5, 8 at%） was coated on the surface of Q195 steel wires by a newly developed continuous coating process. Phase analysis results show that the coating is mainly composed of metallic glass alloy and some other intermetallics. The potentiodynamic polarization tests indicate that the steel wires with metallic glass coating show passivation behavior, and have higher pitting potential and lower corrosion current density than Q195 steel wires. With the increment of Nb content, the passivation region of the metallic glass-coated steel wires become wider while pitting potential is increased. As shown in composition analysis results, it may be attributed to the addition of Nb which has properties of easy passivation and stabilizing the passivation elements of Zr and Ti.
