| 摘 要： | 研究了腐蚀溶液成分和工艺参数对TC4钛合金腐蚀加工速度、表面粗糙度和平整度的影响,利用扫描电镜观察了腐蚀加工前后的表面形貌.研究结果表明:氢氟酸浓度和溶液温度直接决定着腐蚀加工速度,随HF浓度和温度的增加,腐蚀加工速度升高.硝酸具有显著降低表面粗糙度的作用.溶液中的钛离子对腐蚀加工速度以及钛合金零件腐蚀后的表面质量有一定的影响,溶液中钛离子含量较低时,腐蚀加工速度较快,表面平整度较好,随钛离子含量的增加,腐蚀加工速度下降,表面不平整度增加.试样垂直吊挂时,定时翻转并搅拌可以得到均匀腐蚀的表面. |

| Abstract: | In this paper,the influence of ingredients in corrosion solution and process parameters on corrosion rate,surface roughness and surface evenness for TC4 titanium alloy was discussed.Surface morphology was investigated by scanning electron microscopy before and after corrosion processing.The results show that HF concentration and solution temperature directly determined corrosion rate.The corrosion rate was promoted with increasing HF concentration and temperature.HNO3 can significantly reduce surface roughn... |
