“…Key industries such as port machinery, bridge facilities or marine engineering are to some extent heavily involved in the use of Q345 steel [1]. For example, the conveying pipelines made of Q345 steel tend to suffer from sliding wear of conveying materials [2]. It is arduous for the wear resistance of Q345 steel to afford the harsh and changeable service conditions of constructing structures in the architectural realm [3].…”

The synergy of tribology design and surface engineering is vitally important for fulfilling the long-term anti-wear requirements of mechanical equipment. Here, Q345 steel was processed by shot peening (SP) for forming a volcano-like hardened layer (77.72 HV) with high surface roughness (3.77 μm) and low residual tensile stress (210.75 MPa). Then, a zinc-rich epoxy coating was painted on SP-strengthened Q345 steel to construct the double-layer protection. The double-layer system shows excellent tribological behaviors, especially wear resistance being reduced by 76.50% and 38.75%, respectively, with Q345 steel and that sprayed by epoxy coating as a comparison. Crucially, SP layer plays a role in mechanical support, while epoxy coating acts as a cushion to friction force, thus achieving the synergy for enhancing the anti-friction/wear abilities.

In addressing the impact of corrosion on the structural integrity of steel transmission line poles, this study explores the variation in load-bearing capacity under water-related corrosion conditions using the finite element method. The analysis focuses on how corrosion at the base and cross-arm components of steel poles affects their mechanical performance and modal response. The investigation extends to evaluating the structural safety of steel poles under varying levels of water-induced corrosion, specifically considering combined wind load and broken-line load impacts through static equivalent analysis. The corrosion extent is quantified by the material mass loss rate, with material property degradation applied to simulate corrosion effects. Findings reveal that increased corrosion depth and length result in the concentration of stress and strain at affected areas, alongside decreased vibration frequencies, heightening resonance risk under wind loads. Furthermore, as the mass loss rate increases, maximum equivalent stress and elastic strain values rise significantly. This research provides a scientific basis for understanding water-related corrosion effects on steel transmission line poles, offering essential theoretical insights to enhance structural safety.
