Corrosion and fretting wear inevitably occur in wires, which are important parts of cables. To study the wear morphology and surface mechanical behavior of wires for different fretting and corrosion times, a numerical model of fretting wear of wire with different corrosion conditions is established using MATLAB and ABAQUS software’s. First, according to the surface roughness of wires under different corrosion times, the node coordinates in the numerical model are changed to simulate different rough surfaces. Secondly, the wear characteristics of wires under different fretting cycles are obtained by using a cycle jump concept and an ABAQUS user subroutine. Finally, the numerical model is validated using experimental data. The results show that when the corrosion time is 0h, the wear area has a regular oval shape. The wear volumes of wires with corrosion times of 120h and 480h are the largest and the smallest, namely 3.55×10-4 mm3 and 2.7×10-4 mm3, respectively. As wear volume increases, both residual surface contact pressure and stress decrease. When the corrosion time is 0h and 120h, the residual surface contact pressure is maximum and minimum, respectively.
