Origin and evolution of false brinelling and fretting corrosion under rolling conditions

Friction
Rolling bearings working in oscillating applications often suffer from false brinelling and fretting corrosion that limit their service life. At present, the study of oscillation-induced failures is primarily dominated by a large number of sliding and ...

Contact Properties and Wear Behaviour of Nickel Based Superalloy René 80

Metals, 2016
A superalloy traditionally offers excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion or oxidation. However, a superalloy often also needs performance in terms of fretting resistance.

Effect of work-rate on synergy of corrosion and wear of nickel-based 690 alloys under fretting conditions

Results in Engineering
The heat exchange tubes in the secondary steam generator of pressurized water reactor vibrate due to the impact of fluid, which results in collision leading to fretting wear. The work-rate can characterize random vibrations over time.
