摘　　要：内燃机的曲轴是发动机最关键的组成部分之一,其完整性对整个发动机的性能至关重要。曲轴断裂通常由材料缺陷、过度负荷或疲劳破坏引起,这些因素可能导致昂贵的维修和长时间的服务中断。摩擦焊接技术作为一种先进的固相连接技术,因其优越的接头质量和能在不同材料之间提供强烈冶金键的能力而受到关注。该技术通过转动和压力实现接头处材料的塑性变形和摩擦热,从而在不熔化材料的情况下实现焊接。本文探讨了基于摩擦焊接技术的内燃机曲轴断裂修复工艺的优化方法,旨在提高修复效率和延长曲轴的服务寿命。The crankshaft of an internal combustion engine is one of the most critical components of the engine,and its integrity is crucial to the overall performance of the engine.Crankshaft fracture is usually caused by material defects,excessive load,or fatigue failure,which can lead to expensive repairs and prolonged service interruptions.Friction welding technology,as an advanced solid-phase bonding technique,has attracted attention due to its superior joint quality and ability to provide strong metallurgical bonds between different materials.This technology achieves plastic deformation and frictional heat of the material at the joint through rotation and pressure,thereby enabling welding without melting the material.This article explores the optimization method of internal combustion engine crankshaft fracture repair process based on friction welding technology,aiming to improve repair efficiency and extend the service life of the crankshaft.
