摘要
利用ＸＰＳ研究了ＺｒＣｒ＿（２－ｘ）Ｆｅ＿ｘ（ｘ＝１．２，１．４，１．６）的表面组分及化学态，结果表明Ｚｒ在表面偏析，以ＺｒＯ＿２形式存在，而Ｆｅ和Ｃｒ以金属态存在于次表示。用１０１．３５ｋＰａ空气对ＺｒＣｒ＿（２－ｘ）Ｆｅ＿ｘ抗中毒性质进行了研究，发现抗中毒性质随铁含量的增加而增大，当时，抗中毒性质与此相反。
The surface composition of ZrCr_(2-x)Fe_x and chemical valence of atoms were in-vestigated by means of XPS.It was found that segregated on the surface, Zr atoms formZrO_2 with oxygen,and that iron and chromium both exist as metals in the subsurface. Theresistance to poisoning of the alloy was studied in the air of 1 atm. And the results show theresistance to poisoning of the alloy increases with the increasing iron content in it
