计算了CO和H_2与U,UO_2,UO_3和U_3O_8反应的自由焓变化ΔG~0,指出CO-H_2系统能使铀表面趋于比较致密和稳定的单纯UO_2晶体表面,形成“钝化层”,以阻止H_2等进一步向内扩散而导致腐蚀。这个首次提出的抗铀表面腐蚀的理论模型经进一步研究已得到证实。
The free enthalpy change ΔG ~ 0 of reaction between CO and H_2 and U, UO_2, UO_3 and U_3O_8 was calculated. It is pointed out that the CO_2 system can make the uranium surface more compact and stable and form the “passivation layer” To prevent H 2 and other further inward diffusion and lead to corrosion. This first proposed theoretical model of uranium surface corrosion has been further studied.
