【摘要】 通过对循环水泵轴断裂失效的宏观和微观分析,得出该循环水泵轴的失效属于腐蚀疲劳破坏,是弯曲循环载荷和循环水中的Cl~-离子共同作用的结果,并对今后防止这类失效提出了建议.更多还原

【Abstract】 The failure reason of a pump shaft was analyzed by means of optical microscope and scanning electron microscope. The results showed that the failure was caused not only by fatigue but also by chlorion stress corrosion. Some proposals were given in order to prevent from failure of the water-pump shaft.更多还原
