| 中文摘要: |
| 为确定适用于2197铝锂合金的化学铣切工艺,先通过对比实验筛选出适用的碱洗液和化铣液,之后设计正交试验,以化铣试样的表面粗糙度为参数,确定了化铣液的最优配方,并研究了化铣温度和化铣厚度对化铣效果的影响。结果表明:碱洗液以NaOH溶液(NaOH质量浓度10～ 20 g/ L)为好;化铣液各组分的最佳配比为NaOH 200 g/ L,Na2S 35 g/ L,Al3+ 45 g/ L,三乙醇胺50 g/ L;该化铣液的化铣温度以85℃为宜,化铣厚度不宜高于5 mm。 |

| Through comparing the experimental application of the base lotion and chemical milling solution, the pre-treatment process was screened,and then the optimal formula of milling liquid was determined by orthogonal method with the surface roughness as the evaluation parameters,also the effect of chemical milling temperature and the thickness of milling on the chemical milling was studied. The chemical milling process was determined: alkaline lotion with NaOH solution(NaOH concentration of 10～ 20 g/ L)is good;in chemical milling solution the optimum ratio of each component is NaOH 200 g/ L, Na2S 35 g/ L, Al3+ 45 g/ L, triethanolamine 50 g/ L; The chemical milling temperature of 85℃ is suitable, chemical milling thickness should be less than 5 mm. |
