Exponential evolution law of fretting wear damage in low-friction coatings for aerospace components

Abstract:

Friction coefficient evolution in low-friction coatings subjected to fretting wear was measured and described using a power-law relation for the development of Kachanov-type damage parameter as a function of accumulated reciprocal sliding distance. Fretting wear tests were performed using idealised contact geometry and loading conditions similar to those found in aero-engine components. A conventional dry film lubricant coating and a mechano-chemical coating were considered, together with var...
