Nitriding Treatment on the Influence of Overrunning Clutch Holder of Residual Stress

In this paper, the overrunning clutch holder as the research object and the X-ray stress analysis methods are used to consider the nitriding treatment on the influence of overrunning clutch holder of residual stress, and have a research on the influence of nitriding treatment on the residual stress of holder along with different depth. From the test results, it can be found that although the nitriding treatment do not have a obvious effect on the distribution state of the parts of the surface residual stress, but the residual stress values of the surface could be improved with nitriding treatment, then the micro cracks could be effectively suppressed to expand to the inside parts, further, the fatigue strength of parts could be enhanced, in the end the service life of parts could be increased
