| Abstract: | The metallography micro analysis and degree of hardness test to the 18Cr2Ni4WA material of injector valve body forehead broken place had been carried on by using the EPIPHOT300 metallographical microscope image analysis system and VH-5 Vickers hardness tester image analysis system. According to the test result, the mechanism of its broken expiration had been emphatically analyzed and the corresponding improvement measure also has been proposed. |
| Keywords: | injector valve metallographical analysis hardness test expiration analysis |
