摘要

减少摩擦损失是提高发动机效率的一个重要方面。凸轮挺柱机构作为发动机配气机构的一个重要组成部件，在发动机配气机构中的摩擦消耗的能量占比超过了70%，因此针对凸轮挺柱摩擦副的摩擦磨损性能进行研究，是保证发动机拥有良好使用效率的不可或缺的一环。在各种表面处理技术中，激光表面处理技术已经广泛应用于改善材料摩擦性能等方面，在减摩减损方面有着优异表现。本文概述了凸轮挺柱摩擦副磨损机理的研究进展，总结了其摩擦磨损的影响因素，从激光淬火、激光熔覆涂层、激光表面织构3 个方面对凸轮挺柱摩擦副减摩效果进行了分析，可为后续研究者在该方向的研究提供参考；最后结合现有研究与未来需求，针对激光表面处理技术应用于凸轮挺柱的减摩研究做出展望。

Abstract

Reducing friction loss is an important aspect of improving engine efficiency.The cam tappet mechanism， as an important component of the engine gas distribution mechanism， accounts for over 70%of frictional energy consumption in the engine gas distribution mechanism by friction.Therefore，investigating the tribological performance of cam tappet friction pairs is indispensable for ensuring optimal engine operational efficiency.Among various surface treatment technologies， laser surface treatment has been widely applied to improve the tribological properties of materials，demonstrating excellent performance in friction reduction and wear resistance.This paper reviewed recent advances in wear mechanisms of cam tappet friction pairs and summarized key factors influencing their tribological performance.The friction-reduction effect of the cam tappet friction pair was analyzed from three aspects: laser quenching， laser-cladded coating and laser surface texture， which could provide a reference for subsequent researchers in this direction.Finally， combining the existing research and future demands， the prospects for applying laser surface treatment technologies to friction-reduction studies of cam tappet systems were provided.

Key words： cam tappet; friction and wear; laser surface treatment; friction reduction and wear resistance
