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 37LA 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 .…
