Compound Surface Processing Craft Research on Lubrication without Oil or High Pressure Moving Seal PartCHEN Wenyun,HOU Huijun 1. China Shipping Ninth Design Academe Engineering Limited Company, Shanghai 200063, China; 2. Research Institute of Materials Surface, Guangzhou Research Institute of Nonferrous Metal, Guangzhou 510650, ChinaAbstract:The 4102B type special kind engine has a piston pole party that has no oil lubricate to seal part in moving shoes, It has been complexed surface processing, it is improved a bear to wear away function of double seal part effective. This paper emphasized introduces craft research of a piston pole complex surface processing.
