摘要(Abstract)：
通过正交试验以及多指标分析法对2219铝合金的NaOH+Na2S+TEA+Al3+化学铣切溶液配方进行了最优化研究。实验结果表明,当将化铣后试样表面粗糙度作为分析时着重考虑的指标时,化铣溶液的最优配比为160~180g·L-1NaOH,5g·L-1Na2S,60g·L-1TEA,25g·L-1Al3+。当优先考虑化铣速率的影响时,溶液的最有配比为200g·L-1NaOH,14g·L-1Na2S,10~60g·L-1TEA,5g·L-1Al3+。而若同时考虑表面粗糙度和化铣速率两个指标,适用于2219铝合金化学铣切的最优溶液配方则应为200g·L-1NaOH,5g·L-1Na2S,60g·L-1TEA,5g·L-1Al3+,当使用此配比溶液对2219铝合金进行化铣后得到的试样表面粗糙度与化铣速率分别为0.6055μm以及0.1638mm·min-1。
