Cylinder hole by laser quenching, inner and outer round surface can be ion nitriding, the strengthening method can improve the hardness and wear resistance of the cylinder. To improve the anti fatigue strength, nitriding can also improve the ability of the cylinder outer surface anti cavitation.


The cylinder liner is one component of the combustion chamber components, direct contact with the inner wall and the outer wall of the gas, often for cooling the cooling water, so it can bear high heat load, mechanical load and severe corrosion. At the same time, the cylinder still lubrication conditions were very poor and the piston assembly for a dramatic friction we use. The liner material is copper chromium molybdenum alloy cast iron has good heat resistance, thermal conductivity and corrosion resistance. At the same time to just set the nitriding. Increase the wear resistance of the cylinder liner .
