摘要
为研究不同热处理状态对2195铝锂合金化铣性能的影响,通过正交试验的方法,研究了不同热处理状态(T8态与O态)的2195铝锂合金在不同工艺参数下的化学铣切性能。试验结果表明,在不同的工艺参数下T8态的化铣速率均高于O态的,且T8态的侧切率相对O态的更为稳定。同时试验结果表明2195铝锂合金的化铣表面质量与热处理状态有关,O态试样化铣后在肋条位置会有不同程度的蚀沟,而T8态试样化铣后光滑平整,化铣后的表面质量优于O态。
For studying the effect of different heat treatment states on the chemical milling properties of 2195 Al-Li alloy, orthogonal experiments were used to research the chemical milling properties of 2195 Al-Li alloys with different heat treatment states(T8 state and O state) under different process parameters. Results showed that the chemical milling rate in T8 state was higher than that in O-state under different process parameters, and the side cutting rate in T8 state was more stable than that in O-state. Meanwhile, the surface quality of 2195 Al-Li alloy after chemical milling was related to the heat treatment state. The O-state sample had different degrees of etching grooves at the rib position after chemical milling, while the T8-state sample was smooth and flat and had better surface quality after chemical milling.
