内燃机零件疲劳断裂的快速诊断

Quick diagnosing of fatigue break of internal combustion engine parts

基于对零件疲劳断裂断口进行的分析,在不采用电子显微镜的情况下,建立了一套零件疲劳断裂的快速诊断体系,可以快速查找发动机零件断裂原因,及时整改和预防零件故障。

Without using electronic scan microscope,the reason of the fatigue break could be discovered quickly based on the analysis of the surface of fatigue break of different engine parts which could be helpful to correct and prevent this kind of fatigue occuring.
