“…The metallic materials used for the turbines are austenitic stainless steel (over 12% Cr content as an alloy), but the turbine blades can also be made of martensitic stainless steel due to the higher strength of the steel [66,67]. Low-head machine parts are made of weathering steel (Corten steel) and various types of stainless steel [68,69], high-strength steel [56,70], ACSR steel [71], cast steel [68], carbon steel [72][73][74], and ferritic steel [69] (see Section 2.2 for detailed description of metallic materials). Resistance to erosion and cavitation are also important factors to consider for metallic materials used in the hydroelectric sector [66,75,76].…”

The need for a more sustainable and accessible source of energy is increasing as human society advances. The use of different metallic materials and their challenges in current and future energy sectors are the primary focus of the first part of this review. Cryogenic treatment (CT), one of the possible solutions for an environmentally friendly, sustainable, and cost-effective technology for tailoring the properties of these materials, is the focus of second part of the review. CT was found to have great potential for the improvement of the properties of metallic materials and the extension of their service life. The focus of the review is on selected surface properties and corrosion resistance, which are under-researched and have great potential for future research and application of CT in the energy sector. Most research reports that CT improves corrosion resistance by up to 90%. This is based on the unique oxide formation that can provide corrosion protection and extend the life of metallic materials by up to three times. However, more research should be conducted on the surface resistance and corrosion resistance of metallic materials in future studies to provide standards for the application of CT in the energy sector.

Adhesive bonding between steel and carbon-fiber-reinforced polymer (CFRP) composite leads to hybrid structures that combine the high strength and ductility of steel with the excellent specific strength and stiffness of CFRP composite. There is, however, a concern regarding possible galvanic corrosion when steel and carbon fibers are bonded together. One way to overcome this problem is placing glass fiber-reinforced polymer (GFRP) composite between the steel and CFRP composite, creating a more complex steel/GFRP/CFRP hybrid structure. Therefore, experimental and numerical studies on the mechanical behavior of the adhesive bonds between the steel sheet and the GFRP/CFRP hybrid composite were carried out. Among the different failure patterns, mode II was chosen for analysis because metal–polymer composite structures are usually subjected to bending, and debonding may occur due to in-plane shear stress. The tested steel/GFRP/CFRP hybrid structure was made of a hot-formed 22MnB5 boron steel sheet, intermediate single-ply bidirectional GFRP composite, and three-ply unidirectional CFRP composite. Additional mechanical tests were also carried out to determine various engineering constants of the components to simulate the debonding process. A finite element model of the steel/GFRP/CFRP hybrid structure with a typical cohesive interface was established and verified against the experimental data. The results showed that due to the use of various materials, the dominant failure modes in the hybrid structure under bending loading were a brittle fracture of the CFRP composite and debonding between the steel and the GFRP composite. However, the load-bearing capacity of the hybrid structure was five times greater than that of a non-reinforced steel sheet. In addition, its mass was only 28% greater than the non-reinforced steel sheet. The obtained results provided valuable conclusions and useful data to continue further research on the mechanical behavior of steel/GFRP/CFRP hybrid structures.

“…Using special lubrication methods or additives can effectively reduce the friction coefficient and friction losses of rolling bearings, providing good lubrication effects and prolonging the service life of bearings. Among these, materials such as solid paraffin (Dawari et al , 2022), hydrogenated diamond-like carbon coatings (Zhou et al , 2022), titanium alloys (Zhao et al , 2022a), self-lubricating polymer composites (Rodiouchkina et al , 2022; Zhao et al , 2022b), molybdenum disulfide and its composites (Yang et al , 2023; Gokce et al , 2021; Yang et al , 2022; Bhardwaj et al , 2021), polytetrafluoroethylene (PTFE) composites (Gungor and Demirer, 2022; Beckford et al , 2011; Deleanu and Georgescu, 2015; Feng et al , 2021; Lin et al , 2021; Trabelsi et al , 2016), graphene materials (Jin et al , 2023; Mao et al , 2018; Wu et al , 2021a; Jin et al , 2021) and alumina (Al 2 O 3 ) composites (Zhang et al , 2016; He et al , 2020; Tong et al , 2022) have demonstrated excellent anti-wear performance and tribological characteristics. However, the method of storing composite solid lubricants in bearing grooves has yet to receive attention.…”

Purpose The purpose of this paper is to develop a new type of embedded solid self-lubricating thrust ball bearing for conditions where grease lubrication cannot be used and to analyze its tribological performance under different lubrication characteristics (lubrication position, width and filling amount). Design/methodology/approach Lubrication parameters such as position (a), width (W) and filling amount (Q) were considered. Grooves were made on the raceway with a fiber laser and solid self-lubricating materials were applied through scraping. The frictional behavior of the new bearing was analyzed using a vertical test rig and the bearing’s surface topography was examined with a noncontact profilometer to study wear mechanisms. Findings The new inlay thrust ball bearings exhibited excellent lubrication effects and effectively controlled the temperature rise of the bearings. When a is 0 degrees, W is 0.5 mm and Q is 16 mg, the bearing experiences the least wear, and the friction coefficient and temperature are the lowest, measuring 0.001 and 41.52 degrees, respectively. Under the same experimental conditions, compared to smooth bearings without solid lubrication, the friction coefficient decreased by 96.88% and the temperature decreased by 59.74%. Originality/value This study presents a self-lubricating thrust ball bearing designed for conditions where grease lubrication is not feasible. A comprehensive investigation was conducted on its surface morphology, wear mechanisms and tribological performance. This work provides valuable insights into the research of self-lubricating thrust ball bearings.
