Fretting corrosion is a form of accelerated atmospheric oxidation which occurs at the interface of contacting materials undergoing slight, cyclic relative motion. In electric contacts involving non-noble metals, fretting action can cause rapid increases in contact resistance, proceeding to virtual open circuits in a matter of minutes in the worst cases. Experimental results of resistance increa...

Commercial transport aircraft are required to operate under the concept of damage tolerance. Because of the structural redundancy and the crack arrest capability, the current fleet of commercial aircraft was initially designed to have sufficient residual strength to sustain discrete source damage. However, fatigue damage during the life of an aircraft can significantly reduce the residual stren...

Abstract The fretting wear among the steel wires aggravates wire rope’s fatigue damage, affects service performance of ropes, and threatens mine hoisting safety. In this paper, practical friction behavior mechanism in rope are investigated. A series tests were carried out on multiple helical contact tension-torsion coupling under different parameters, twisting lubrication conditions by self-mad...
