Abstract
Surface wear and corrosion affect the service performance of steel wire rope. They usually appear alternately and interact. In this paper, the friction and wear properties of wire ropes with different corrosion types were investigated. Then, the interactions of the corrosion and wear on the residual strength of the rope samples were analysed. The results show that the corrosion had a strong influence on the coefficient of friction (COF) and temperature rise of the wire rope. Additionally, surface corrosion reduced the anti-wear properties and fatigue resistance of the rope. The effect of sulfuric acid corrosion was the most obvious, followed by that of sea-water and fresh water. The maximum breaking force of the wire rope with sulfuric acid corrosion decreased rapidly with the wear time, from approximately 49.9 kN–41.5 kN. Furthermore, under tensile load, the plastic deformation of the rope wires was closely related to the surface wear and corrosion condition. This study can provide basic data for the safe use and maintenance of steel wire rope.
