The Technology of Laser Honing Applied in Distinctively Improving The Lubrication of Frictional Units

摘要

Cylinder bore (sleeve) and piston ring is a pair of the most essential friction units in an internal combustion engine, which directly affect the life span and the properties of the internal combustion engine. The desired dimension, shape and roughness can be obtained by traditional mechanical machining and then The surface of cylinder bore is hardened by the laser beam.
