This article presents a comparison between the performances of two chemistries synthetic oil lubricants, polyalphaolefins (PAOs), and perfluoropolyethers (PFPEs) when applied on gold-plated electrical contacts operating at contact loads 9.8 centiNewton (cN) experiencing fretting-induced degradation. Performance assessment was done using resistance coefficient friction behavior surface’s ...

Abstract Fretting in the partial-slip and gross-slip regimes under a constant normal load is considered. The tangential force—displacement relations for forward backward motions are described based generalized Cattaneo—Mindlin theory of contact Masing’s hypothesis on modelling hysteretic loop. Besides critical force displacement parameters (characterizing triggering sliding), model includes one...
