Failure Analysis of Axle Sleeve Made from 2Cr13 Steel
The 2Cr13 axle sleeve,used in N52 water pumps,suffered wear after being tested for a relatively short time and fractured when it was beat under the dynamic load.Optical metallographic microscopy,scanning electron microscopy (SEM) and Vickers hardness tester for the fractured 2Cr13 axle sleeve were used to determine the most probable causes of the failure.The results showed that the failure was mainly due to the inappropriate technological parameters of high frequency induction heating and a large amplitude rotor vibration.Meantime,cracks were easily found not only close to the frayed surface but also in the inner part contributed to the inappropriate parameters.Finally,the proper protections were advised to be used for preventing this type of failure for the axle sleeve from happening again in the further.
