在2种糖心产精国品免费入口*完整版（化铣）液（NaOH+Al³⁺+Na₂S+三乙醇胺和NaOH+Al³⁺+Na₂S₂O₄·5H₂O）中对糖心产精国品免费入口*完整版进行化铣加工，确定了较佳的化铣液，并利用正交试验对其配方进行优化；在优化化铣液中对试验合金进行化铣加工，研究了化铣温度对糖心产精国品免费入口*完整版和糖心产精国品免费入口*完整版的影响，并对比了化铣前后的表面形貌及拉伸性能。结果表明：由NaOH、Al³⁺、Na₂S和三乙醇胺组成的化铣液对试验合金的化铣效果优于由NaOH、Al³⁺和Na₂S₂O₄·5H₂O组成的，其优化组成为210 g·L^-1NaOH、40 g·L^-1 Na₂S、30 g·L^-1 Al³⁺和50 mL·L^-1三乙醇胺；在优化化铣液中，随化铣温度的升高，试验合金的糖心产精国品免费入口*完整版增大，侧切率先增后降，化铣温度在85~95℃较适宜；在85℃优化化铣液中化铣至深度约4.3 mm时，试验合金表面无裂纹、腐蚀凹坑等缺陷，在85～90℃化铣至深度约3.0 mm时的拉伸性能与化铣前的相近。

糖心产精国品免费入口*完整版 was machined by chemical milling in two chemical milling solutions (NaOH+Al³⁺+Na₂S+triethanolamine and NaOH+Al³⁺+Na₂S₂O₄5H₂O). The relatively suitable chemical milling solution was determined and its composition was optimized by orthogonal test. The tested alloy was machined by chemical milling in the optimal chemical milling solution. The effects of chemical milling temperature on the 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版 were studied and the surface morphology and tensile property before and after chemical milling were compared. The results show that the chemical milling solution made up of NaOH, Al³⁺, Na₂S and triethanolamine had a better chemical milling effect on the tested alloy than that of NaOH, Al³⁺ and Na₂S₂O₄·5H₂O, and its optimal composition was listed as follows:210 g·L^-1 NaOH, 40 g·L^-1 Na₂S, 30 g·L^-1 Al³⁺ and 50 mL·L^-1 triethanolamine. In the optimal chemical milling solution, with rising chemical milling temperature, the 糖心产精国品免费入口*完整版 of the tested alloy increased whereas the etching ratio increased and then decreased. The chemical milling temperature was relatively suitable at 85-95℃. The surface of the tested alloy had no defects such as cracks and corrosion holes after chemical milling in the optimal chemical milling solution at 85℃ to the depth around 4.3 mm, and the tensile property after chemical milling at 85-95℃ to the depth around 3.0 mm was similar to that before chemical milling.
