Problems of Piston Ring Surface Infiltration Pottery Craft and Improving Measures

Objective Based on the problems existing in the current piston ring ceramic membrane process, this paper proposed a method to improve the infiltration pottery power supply, to help the processing of piston ring to meet the requirements of industrial application, and meanwhile to improve the processing efficiency. Methods The main factors affecting the surface of piston ring in the preparation of ceramic membrane process were discussed by PECVD. Based on these factors, the effects of processing under different parameters for infiltration pottery power supply discharging were compared. Results Under the optimal combination of discharge parameters, the processing effect by this kind of improved power supply was as good as the traditional power supply, and the processing efficiency was also improved. Conclusion Asymmetric pulse power supply can replace traditional power supply with high power consumption for making the piston ring surface ceramic.
