The wear-out powders were generated in the contact part of wing dovetail and wheel dovetail. The occurrence of a crack, because of the fretting fatigue occurs on the contact edge between wing dovetail and wheel dovetail, is found as shown in Fig.8, and the crack progresses to the wing dovetail side.
The black square symbols indicate the test pieces without WJP, in which the crack does not occur.


Furthermore, the life expansion of fretting fatigue occurred in the blade dovetail of gas turbine compressor was investigated by using the technology of WJP in air, which was developed in this study. The WJP in air was performed to the root part on both sides of the wing dovetail test piece (Fig.9).
