摘　　要：非晶合金纤维在0.5mol/L H2SO4和0.1mol/L HCl溶液中均能发生自发钝化,且钝化区宽、维钝电流密度低。在0.5mol/L H2SO4溶液中钝化区宽度为1 336mV,维钝电流密度为3.4×10-6 A·cm-2;在0.1mol/L HCl溶液中钝化区宽度为1 407mV,维钝电流密度为1.3×10-6 A·cm-2。比较非晶合金纤维和不锈钢纤维2种混凝土增强材料的耐腐蚀性能,非晶合金纤维的耐腐蚀性要优于不锈钢纤维,非晶合金纤维优良的耐腐蚀性能源于表面形成一层致密而稳定的钝化膜。The amorphous metal fibers show high corrosion resistance with a lower passivation current density and a wide passive region in 0.5 mol/L H2SO4 and 0.1 mol/L HCl solutions.There are passivation current density of3.4×10^-6 A·cm^-2 and a passive region of 1 336 mV in 0.5mol/L H2SO4 solution.There are also passivation current density of 1.3×10^-6 A·cm^-2 and a passive region of 1 407 mV solution in 0.1mol/L HCl solution.The corrosion behaviour of amorphous metal fibers is compared with stainless steel fibers.Amorphous metal fibers exhibit more superior corrosion resistance than that of stainless steel fibers.The superior corrosion resistance of amorphous metal fiber is attributed to the formation of a dense and stable protective passive film.
