8-98096676-0 STD Piston Ring Set For ISUZU 4JJ1-T 4JK1-T 8980966760

Product Description

The piston ring is a metal sealing ring with certain elasticity, which is assembled in the Piston Ring groove and seals the cylinder together with the piston. The piston ring works in the high temperature, high pressure and the high-speed movement conditions, so the materials we used for the piston rings have good wear resistance, heat resistance and thermal conductivity, while having sufficient strength, elasticity and impact toughness.

Surface Treatments for Piston Rings

The surface treatment of piston rings can greatly improve its performance. It helps to improve durability of the piston rings, and also affects their function, wear resistance, and friction characteristics.

Here is the common surface treatments for piston rings,

1, Phosphating: This is a chemical treatment to improve wear resistance, which can help to protect the material from corrosion, and provides a good surface for oil to adhere to.

2, Chrome Plating: A thin layer of chromium applying to the surface of the piston ring to improve its hardness and wear resistance. Chrome plating also provides good corrosion resistance and helps to reduce friction between the piston ring and the cylinder.

3, Nitriding: This is a heat treatment that involves introducing nitrogen into the surface of the piston ring to form a hard, wear-resistant surface layer. Nitriding can improve the wear resistance and fatigue strength of the piston ring and also reduce friction.

4, Coating: This involves applying a layer of coating material to the surface of the piston ring to improve its wear resistance and reduce friction. Common coatings include molybdenum disulfide, tungsten disulfide, and diamond-like carbon (DLC).
