The development at home and abroad in laser quench for improving wear-resistant properties of cylinder liners is introduced. The key technologies, the strengthening mechanism, laser processes, as well as the quenching mode are analyzed. The effect of laser quench tracks and pre treatments at the specimen surface upon strengthening effectiveness, and the experimental results of different processed cylinder liners and bodies are summarized. The result shows that under the conditions of optimum processes, not only the life of laser processed cylinder liners is prolonged but the wear resistant properties of the pairing un processed piston rings are improved by 50%, and the life of both the cylinder liner and the body increases by 2～3 times.
