酸洗对基体表面粗糙度的影响

Effect of Pickling on Surface Roughness of Matrix

本文研究了在前处理酸洗液中加入粗化剂,钕铁硼基体表面获得良好粗糙度的前处理酸洗工艺。试验结果表明,合适的酸洗粗化剂浓度是钕铁硼基体获得良好粗糙度的关键。用有机晶体粉末作为粗化剂可以获得粗糙度良好的基体表面。同时还研究了酸洗浓度、酸洗温度以及酸洗时间对钕铁硼基体表面粗糙度的影响。

In this paper, the pretreatment pickling process of NdFeB substrate surface with good roughness was studied by adding roughening agent into the pretreatment pickling solution. The test results show that suitable concentration of pickling roughening agent is the key to obtain good roughness of NdFeB matrix. The matrix surface with good roughness can be obtained by using organic crystal powder as roughening agent. The effects of pickling concentration, pickling temperature and pick-ling time on surface roughness of NdFeB substrate were also studied.
