- 摘要:
- 为满足使用环境对液压缸活塞销耐磨性提出的较高要求，采用两种方法对活塞销样件进行高温锰系磷化处理，表征和测试了锰系磷化处理后样件的形貌和性能，并与原始样件进行了对比。结果表明：采用高温锰系磷化处理后，活塞销样件宏观上都呈黑色，其显微硬度有不同程度的提高，耐磨性能也有所改善。其中，在表调处理后再进行高温锰系磷化处理对于提高活塞销样件的耐磨性能效果最好。
- Abstract:
- In order to meet the high requirement of using environment for the wear resistance of piston pin for hydraulic cylinder, the piston pin samples were treated by high temperature manganese phosphating with two different methods. The morphology and properties of the samples after manganese phosphating treatment were characterized and tested, and were compared with that of the original sample. The results showed that the piston pin sample after high temperature manganese phosphating treatment show light black at the macro level, and its microhardness and wear resistance have been improved. It was the best effect to improve the wear resistance of piston pin samples to be treated with high temperature manganese phosphating after surface conditioning treatment.
