摘　　要：为了对在高温、磨损工作条件下失效的零件进行表面修复，我们在研制的奥氏体基沉淀强化型焊条基础上，加入稀土元素钇，改善其堆焊层性能。进而研究了预处理对堆焊层组织、性能的影响。In order to repairing of used parts worked in condition of high temperature and wearing,based on development of austenite matrix surfacing electrode,the properties of surfacing layer could be improved by addition of rare earth element Yttrium in the electrode and the influence of pretreatment process on structure and properties of surfacing layer with this electrode was studied in this paper.
