本文介绍了活塞环在镀硬铬生产过程中，用“液体抛光”法取代镀前通常沿用的酸、碱处理和镀后刻蚀松孔处理，使得镀铬工艺流程大为简化。净化镀液，提高生产率，大大减少了“三废”的危害性，对搞好环保具有重要意义，同时，由于环被镀表面受到液体抛光时压力的喷射。表面产生压应力，从而提高了活塞环的耐磨性和镀层与基体的结合力，以及疲劳强度，延长了环的使用寿命．
This paper introduces the piston rings in the hard chrome plating production process, using the “liquid polishing” method instead of the usual plating before the acid, alkali treatment and post-plating etching loose hole processing, making the chrome process greatly simplified. Purification of bath, increase productivity, greatly reducing the “three wastes” of the harmfulness, to improve environmental protection is of great significance, at the same time, due to ring plated surface by the liquid when the jet pressure polishing. The surface of the compressive stress, thereby enhancing the wear resistance of the piston ring and the coating and the substrate bonding strength, and fatigue strength, extending the life of the ring.
