【摘要】:探讨了TC1钛合金腐蚀加工速度和质量的影响因素,测试了腐蚀加工后TC1钛合金的力学性能。氢氟酸浓度增加,加工速度提高;硝酸浓度较低时,腐蚀溶解占主导地位,浓度较高时,钝化起主要作用,当硝酸与氢氟酸的体积比为2时加工速度达到最大值;钛合金腐蚀加工速率与温度基本呈线性关系,加工时温度控制范围为28~30℃。复配添加剂可降低界面张力,它们的协同效应能够提高过渡区圆角质量、表面光亮度和腐蚀均匀性。腐蚀加工对TC1钛合金拉伸性能影响较小。腐蚀加工后的疲劳性能优于机械加工后的疲劳性能,其疲劳裂纹起源于加工面R圆角根部区域。
[Abstract]:The influence factors of corrosion processing speed and quality of TC1 titanium alloy were discussed, and the mechanical properties of TC1 titanium alloy after corrosion processing were tested. When the concentration of hydrofluoric acid increased, the processing speed increased, and when the concentration of nitric acid was low, corrosion and dissolution dominated, and when the concentration was higher, passivation played a major role, and the processing speed reached the maximum when the volume ratio of nitric acid to hydrofluoric acid was 2. The corrosion rate of titanium alloy is linearly related to temperature, and the temperature control range is 2830 鈩,
