提高镀铬活塞环铬层表面质量的试验研究

Test for Improving the Plating Quality of Chrome-Plated Piston Rings.

镀铬活塞环是内燃机中的重要零件,本文以其中最难加工的镀铬油环为例,对如何选择最佳工艺参数来提高其铬层表面质量进行了六个方面的试验与研究,获得了一套较理想的工艺数据,使铬层表面质量合格率提高了24%,使废品率从原先的26%下降到2%以下,在生产实践中取得了满意的效果。

Taking the chrome-plated oil ring of piston as an example, the author makes an investigation in six aspects on how to select the optimum technological parameters to improve the plating quality, and works out a set of ideal technological parameters, which achieve satisfactory results in shop practice,
