摘要
针对轴类零件在使用过程中常会出现磨损的情况,对轴类零件的磨损及其原因进行了分析,介绍了近年来轴类零件修复技术的发展,包括喷涂技术、滚花技术、镀覆技术和堆焊技术,并总结了这些修复工艺的特点和应用情况。喷涂技术适用范围广,可以实现零部件表面的一般修复,其缺点是修复层与基体间的结合强度低;滚花技术适用于超差量不大、要求不太严格的固定配合零件的修复加工;镀覆技术适用范围广,镀后不变形,结合强度较喷涂高;堆焊修复技术结合强度高。这为磨损轴类零件的修复方法的选用提供了借鉴意义。
According to abraded shafts in the use ,this text analyzes abrasion cause of shafts.It briefly introduces repairing technology reeently and summarizes characteristics and applications of various repairing techniques,including spraying method,knurl method, plating method and surfacing welding method.Spraying method has wide range of application and repairs shafts generally,its disadvantage is low bonding strength;knurl method is applicable to shafts of little abrade and strict ;plating method has wide range of application and without deformation,bonding strength is higher than spraying method：bonding strength of surfacing welding method is the highest in all methods.It provides a reference for selecting method of repairing abraded shafts.
