“…When the speed is fast enough, shear stresses has superimposed with each other and enlarged, RCF lifetime has reduced due to the cracks generated and expensed [38] . This concludes has been certificated by other study [50,[56][57] . Moreover, high revolving speed accelerates wear and fatigue cracks initiation as shown in Fig.…”

The service condition determines the Rolling Contact Fatigue(RCF) failure mechanism and lifetime under ascertain material structure integrity parameter of thermal spray coating. The available literature on the RCF testing of thermal spray coatings under various condition services is considerable; it is generally difficult to synthesize all of the result to obtain a comprehensive understanding of the parameters which has a great effect on a thermal spray coating's resistance of RCF. The effects of service conditions(lubrication states, contact stresses, revolve speed, and slip ratio) on the changing of thermal spray coatings' contact fatigue lifetime is introduced systematically. The effects of different service condition on RCF failure mechanism of thermal spray coating from the change of material structure integrity are also summarized. Moreover, In order to enhance the RCF performance, the parameter optimal design formula of service condition and material structure integrity is proposed based on the effect of service condition on thermal spray coatings' contact fatigue lifetime and RCF failure mechanism. The shortage of available literature and the forecast focus in future researches are discussed based on available research. The explicit result of RCF lifetime law and parameter optimal design formula in term of lubrication states, contact stresses, revolve speed, and slip ratio, is significant to improve the RCF performance on the engineering application.

“…Because of the friction of wheel/rail interface, the wear damage has become increasingly severe [1,2]. The increase of axle load leads to excessive wear of wheel/rail materials and remarkably decreases the service life of wheel/rail system.…”

“…The geometric sizes of rollers are determined by means of the Hertzian simulation rule [1,31,32], i.e. both the maximum contact pressure and the ratio of the semi-major axis to the semi-minor axis of the contact path in the experimental condition is same as that in the practical, which is shown in Eqs.…”
