摘要

The corrosion of aluminium in concentrated LiNO3 solution at high temperature was studied with aweight loss method. The effects of concentration, temperature, pH and Li2CrO4 on corrosion rates wereinvestigated. Results indicated that increasing concentration of LiNO3 had opponent effects onaluminium corrosion. Elevating temperature and pH could increase the corrosion rate. An incompacthydroxide film was observed on the surface of aluminium in LiNO3 solution. The corrosion waseffectively depressed by adding inhibitor Li2CrO4, where a compact passive film comprising Al(OH)3and Cr2O3 may be formed. The corrosion rate of aluminium in LiNO3 solution was much smaller thanthat in LiBr solution.
