Abstract

PURPOSE:To enhance the nodular corrosion resistance of a Zr alloy by forming an oxygen diffused layer in the vicinity of the surface of the Zr alloy. CONSTITUTION:An oxygen diffused layer having about 1mum-1mm. thickness is formed in the vicinity of the surface of a Zr alloy such as an alloy consisting of, by wt., about 1-1.8% Sn, about 0.1-0.2% Fe, <= about 1.8% Ni, <= about 0.2% Cr and the balance Zr. In order to form the layer, the Zr alloy is allowed to stand in an oxygen atmosphere at about 500-1,000 deg.C under about 1X10<-3>-1X10<-4>mm.Hg for about 1-8hr.
