摘要
应用化学热力学及动力学的基本原理,在阐明铝合金中气体反应行为基础上,根据铝合金的吸氢及析氢机理,从理论上分析了铝合金中针孔成因,进而得出了针孔严重程度的定量判据式(即计算模型)。
In this paper, the fundamentals of chemical thermodynamics and dynamics are used to analyze the behaviors of reactions of gaseous matter in Al - alloys. A theoretical explanation is given as to the cause of formation of pinholes in Al - alloys on the basis of the mechanism of hydrogen - absorption and hydrogen - separation. Further, a quantitative criterion of the pinhole degree is set up.
