摘 要:The corrosion resistance ofZr-1Nb alloy was compared with that of Zr-Sn-Nb-Fe and Zr-4 alloys, and the ef fect of hydrochemistry on the corrosion resistance of Zr-1Nb alloy was discussed. Experimental results show that niob ium oxide is partly soluble in LiOH aqueous solution. Therefore, when Zr-1Nb alloy is corroded in LiOH aqueous sol ution, a soluble niobate produced by the reaction between the corrosion products of β-Nb particles and LiOH results in the formation of pores in the zirconium oxide films and causes the degradation of the corrosion resistance ofZr- 1Nb alloy tested in LiOH aqueous solution.
