Dissipated energy and fretting damage in CoCrAlY-MoS₂ coatings

Abstract:

This paper describes fretting wear behaviour of low friction CoCrAlY-MoS₂ coatings on titanium alloy substrates in terms of dissipated energy and friction coefficient. Experimental characterisation was achieved by measuring the friction coefficient vs fretting cycles, or slid distance. Test results were analysed using exponential evolution functions for fretting damage. Dissipated energy was derived, and predicted and measured values compared. Quantitative evaluation of the fretting damage wa...
