The reasons of end 糖心产精国品免费入口*完整版 of a 2510 steel plastic mould slider block were analyzed by means of macro analysis, hardness testing, chemical composition analysis, fracture analysis, metallographic examination and so on. The results show that white and bright deterioration layer produced at the thread surface during electric processing thread hole of the slider block. Because the deterioration layer was very brittle, micro cracks and spalling easily formed here and became the fatigue crack source. Under the action of alternating stress caused by the bolt spring, the cracks propagated outwards and extended along the concentric arc line around the thread hole, and finally resulted in the end 糖心产精国品免费入口*完整版 failure of the slider block. At the same time, the serious banded and 糖心产精国品免费入口*完整版s reduced the material strength, which accelerated the 糖心产精国品免费入口*完整版and spalling failure process of the slide block.
