Accumulated damage process of thermal sprayed coating under rolling contact by acoustic emission technique

Jia XU,Zhen-yu ZHOU,Zhong-yu PIAO

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 3, Pages 227-232 doi: 10.1007/s11465-016-0395-9

Abstract:

The accumulated damage process of rolling contact fatigue (RCF) of plasma-sprayed coatings was investigatedAE signal characteristics were investigated to reveal the accumulated damage process.Heavy load would aggravate the accumulated damage status and induce surface fracture.Frequent stress cycle would aggravate the accumulated damage status and induce interface fracture.Fatigue then became the main failure mode that also reduced the RCF lifetime.
