Komatsu Engine Piston Ring Materials

Piston rings are made from high-strength materials, such as ductile casting iron, Cr-Mo-Cu casting iron, vermicular casting iron and high strength grey casting iron, forging steel, carbon steel or advanced materials with good wear resistance. The choice of material depends on the specific engine's requirements and design.

Piston Ring Hardening Process

Cam Turning, Special Periphery Lapping, AE Hard-Chromium Plating Process, Ceramic Chrome Plating, Phosphating Process and so on.

Piston Ring Surface Treatment

1, Manganese Phosphate: which offers improved break-in and better wear resistance.

2, Nitride Coating: Nitride coatings offers a hard coating on yourpiston ring, superior wear resistance and lower coefficient of friction for cast iron piston rings. Nitride coating hardens all surfaces of the piston ring or seal for increased wear resistance.

3, Zinc Phosphate: Zinc Phosphate coating on cast iron piston rings can help break in components subject to wear and help prevent galling.

4, Wax Coating: Standard rust preventative coating applied to all piston rings and seals if no special coatings or plating’s are asked for.

5, Chrome Plating: Chrome plating on cast iron piston rings and seals is hard, prevents galling and wears very well. Primarily used on cast iron piston rings and seals.

Piston Ring Functions
Piston rings seal the gap between the piston and the cylinder wall. They prevent the escape of combustion gases from the combustion chamber into the crankcase and regulate the distribution of engine oil.

Compression Rings:

Compression rings are located near the top of the piston and are primarily responsible for sealing the combustion chamber during the compression and power strokes. They maintain compression, ensuring efficient combustion.

Oil Control Rings:

Oil control rings are typically located below the compression rings and are responsible for regulating the distribution of engine oil along the cylinder wall. They prevent excessive oil from entering the combustion chamber
