piston ring improved abrasion-proof |
| abstract |
A piston ring having improved wear resistance according to the present invention is a piston ring that reciprocates along the inner wall of a cylinder liner. The piston ring includes at least one of spherical graphite cast iron precipitated on a pearlite base and worm- And a stator-type process structure made of a special metal. Thus, it is possible to reduce the cost of the plating process by providing a high hardness and abrasion resistance without the chromium plating process, and to improve the productivity. In the process of friction with the cylinder liner during the reciprocating operation, It is possible to provide a piston ring that is environmentally friendly and can improve the wear resistance, which can prevent the piston ring from being generated. |
