Special Issue Information

Dear Colleagues,

Steel wire ropes, due to their capacity to support large axial loads with comparatively small bending or torsional stiffness, have been widely employed in various engineering applications, such as coal mine hoists, bridges, drilling rigs, cranes, lifts, sea mooring lines, aerial ropeways and ski lifts. Nowadays, attributed to the harsh application conditions of an ultra-long carrying distance, ultra-large load, ultra-high running speed of steel wire rope, and complex environment conditions (ultraviolet radiation, alternating temperature and humidity, rain, corrosive gas, corrosive liquid and other environments), new challenges are being faced in terms of how to ensure and improve the service safety and reliability of steel wire rope.

Structurally, hoisting rope is twisted tightly between strands and strands, wires and wires. The combined roles of cyclic stretching, bending and torsional loads, as well as complex and harsh environmental conditions, easily result in wear, corrosion, fatigue crack initiation, propagation and final fracture, which accelerates the failure of the rope and even causes catastrophic rope breakage accidents.

Lubrication and corrosion protection are assumed to be the most effective methods to minimize wear, corrosion and fatigue degradation and thereby prolong the service life of steel wire rope. Therefore, it is of great importance to select new and advanced lubrication materials, surface coating materials and anticorrosion measures for rope wires under complex and harsh environmental conditions in order to ensure proper friction and lubrication states between contact pairs.

The current Special Issue aims to bring together contributions from world-leading scientists working in the fields of rope tribology, lubrication and corrosion protection, with the goal of deepening our understanding on how best to prolong the service lives of steel wire ropes in distinct engineering backgrounds. Contributions are welcome from all scientists working in lubrication, corrosion, tribology and other areas related to steel wire ropes.

The cable system is an important bearing element of a bridge with stay cables or slings and a matter of major concern in the safety of the bridge structure. Bridge cables are vulnerable to corrosion induced by leakage and soaking during their service life. To solve this problem, and based on the idea of proactive control by means of the impressed current cathodic protection (ICCP) of bridge cables, this study designs and develops an ICCP system device for bridge cable protection. In this study, an accelerated corrosion test was conducted to test the ICCP system of steel wires inside the cables and the cables under acid rain conditions. The corrosion protection behavior of ICCP was analyzed to reveal the corrosion protection mechanism of bridge cable ICCP. The results show that in the cable ICCP system, the impressed current generated by a more negative voltage may improve the efficiency of corrosion protection, but an excessively negative voltage may cause hydrogen embrittlement of the cable steel wire due to overprotection. The rational range of −1.13 V to −1.15 V was set as the result of the overall consideration. Within this range, the cable is subject to the joint protection of ICCP and sacrificial anode cathodic protection (SACP). Corrosive products can delay the development of cable corrosion to a certain degree; the SACP protection efficiency of the galvanized coat reduces gradually with corrosion development; and cable ICCP protection efficiency increases gradually. The ICCP for cable corrosion protection is transformed from joint protection using both a sacrificial anode and impressed current into protection, mainly using an impressed current. Full article
