以硼代替部分碳可以大大改善铁基非晶的耐蚀性,尤其是在饱和H_2S的酸性介质中其耐蚀性有显著提高,借助XPS分析发现硼在非晶表面富集形成B_(10)H_(14)化合物,抑制了氢向基体内部的扩散,降低铁基非晶材料的氢致破坏敏感性。
A great improviment on the corrosion resistance of Fe-Cr-P-C amorphous alloy bysubstituting boron for carbon can be made especially in an acid solution saturated with H_2S. Itwas confirmed by XPS analysis that the boron enriches in surface layer of the amorphous alloyand reacts with hydrogen to form B_(10)H_(14). Thus, the hydrogen intrusion into substrate may beprevented and the suscptibility of the amorphous alloy to hydrogeninduced destruction may begreatly decreased.
