| 中文摘要: |
| 目的 研究某产品在热处理后,表面存在的附着物对后续磷化膜质量的影响。 方法 将原热处理工艺中采用的三碱清洗剂更换为除油效果更好的 MT-29 清洗剂,用碱水清洗后,将一次热水洗改为连续两次热水洗,确保零件表面无异物。 结果 工艺改进前,磷化后的零件 80% 以上存在起皮现象,需要反复打磨,工艺改进之后,一次磷化通过率达到了 100% ,电泳涂漆质量满足产品要求。 结论 对成品热处理零件,三碱清洗剂对淬火油的清洗效果不佳,应采用专用的除油清洗剂;热水洗对成品热处理零件表面质量有一定的影响。 |
| 英文摘要: |
| Objective To study the effects of the surface attachments of a product after heat treatment on the quality of phosphate coating. Methods The three alkali cleaning agent used in the original heat treatment process was replaced by the MT-29 cleaning agent oil with better removing effect,and after the alkali washing, the frequency of hot water washing was increased from once to twice, to ensure that no foreign body remained on the surface of the parts. Results Before the optimization of the process, more than 80% of the parts after phosphating showed signs of peeling, requiring repeated grinding,while after the improvement of the process, the pass rate after one phosphating step reached 100% , and the electrophoretic coating quality met the product requirements. Conclusion Experimental results showed that for the finished parts after heat treatment, the three alkali cleaning agent had poor cleaning effect on the quenching oil, instead a special oil cleaning agent should be used. Hot water washing had certain effects on the surface quality of parts after heat treatment of the finished product. |
