摘　　要：气体碳氮共渗相对于渗碳、渗氮,碳氮共渗具有一定的工艺优势,且易获得高的力学性能。但生产中发现此工艺在处理非均匀截面的套筒类零件时易发生较大形变,本文着重分析其形变原因,并提出改进措施。Relative to the carburizing,nitriding and carbonitriding process,gas carbonitriding has certain craft advantages and can obtain better mechanical property.But sleeve parts of non-uniform section often appeared large deformation when gas carbonitriding process had been used in production.So its deformation reasons are analyzed in this paper,and the improvement measures are advanced.
