Cylinder used in laser surface strengthening method 
and quenching and inner and outer round surface can be ion nitriding. The 
strengthening method can improve the hardness and wear resistance of the 
cylinder sleeve. To improve the fatigue strength. The nitriding treatment can 
also improve the ability of cylinder excircle surface anti 
cavitation.
	
The  Cylinder liner 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 resi…
