摘　　要：在内氧化动力学实验的基础上，研究了铝质量分数为0．19％、0．42％、0．72％和0．94％的铜铝合金平板形试样在1023K、1123K、1223K和1273K温度下的内氧化动力学，并采用定量金相技术测量了内氧化层的深度，推导了平板形状铜铝合金试样的内氧化动力学方程。经内氧化实验检验证明，该方程可以较精确的描述平板形状铜铝合金的内氧化动力学。基于该方程和内氧化深度测试，计算出了氧在铜中的渗透率。Experimental investigations on the kinetics of internal oxidation of Cu-Al alloy plates, containing up to 0.94% mass pct Al were investigated around the temperature range 1023K to 1273K. The kinetic equation has been derived to describe the internal oxidation of Cu-Al alloy plates .The derived equation was checked experimentally by means of measuring the oxidation depth with different internal oxidation time. The results show that the derived equation go well with the kinetics of internal oxidation of Cu-Al alloys. Based on the equation and the oxidation depth measurements, the permeability of oxygen in solid copper has been obtained respectively.
