采用增重法和电化学方法分别研究了金属铀表面经CO处理后的抗热氧化腐蚀能力和抗化学介质腐蚀的能力。结果表明 :金属铀表面经CO处理后的抗氧化能力有所提高 ,抛物线氧化阶段其氧化速率比未处理样品的氧化速率低 2 5 %～ 60 % ;电化学研究表明 :金属铀表面经CO处理后 ,其抗化学介质腐蚀的能力增强 ;在实验所用CO剂量范围内 ,其抗蚀性随CO剂量的增加而增强
The effects of thermal oxidation corrosion resistance and chemical corrosion resistance on the surface of uranium metal after CO treatment were studied by using the methods of weight gain and electrochemical. The results show that the oxidation resistance of the surface of uranium metal treated by CO is improved. The oxidation rate of the uranium surface is 25% -60% lower than that of the untreated sample in the parabolic oxidation stage. Electrochemical studies show that the surface of uranium metal is treated by CO , Its ability to resist corrosion of the chemical medium is enhanced; its corrosion resistance increases with the increase of CO dosage in the experimental CO dosage range
