热处理工艺过程简介及失效模式案例浅析

Talk about heat Treatment Technology Process and Failure Mode Abstract

金属热处理是机械制造的重要工艺之一。热处理过程是一个特殊过程,其优势是不改变工件的形状和整体的化学成分,而是通过改变工件内部的显微组织,或改变工件表面的化学成分,赋予或改善工件的使用性能。通过介绍热处理工艺过程及其主要的过程失效模式,以期为热处理零件的质量管理工作提供帮助。

Metal heat treatment is one of the important processes in the machinery.The heat treatment process is a special process,its superiority is does not change the work piece the shape and the whole chemical composition,but through change the work piece interior’s Microstructure,either change the work piece surface’s chemical composition,entrusts with or the improvement work piece operational performance.This article through the introduction heat treatment technological process and the main process failure mode,provides the help by the time to the heat treatment components’ quality control work.
