“…Hydrogen-induced wear as one of the processes leading to the fractures of the surfaces of metallic friction elements under conditions of electrothermomechanical friction is caused by the phenomenon of breaking of hydrocarbon bonds with hydrogen release followed by its diffusion into the surface layers of steels and, hence, their hydrogen embrittlement [1][2][3][4][5]. In particular, it was established that the sizes of the products of wear after the hydrogenation of specimens are much larger than prior to the hydrogenation (the linear sizes are different by 5-6 times) [1][2][3].…”

“…We have established that high-nitrogen steels can hold a layer of adsorbed layered lubricants on their surfaces for several hours (in the absence of lubrication) [25,26]. This feature is associated with the characteristics of the surface layer formed in a number of technological operations.…”

In this study, modern nitrogen steels used for the manufacture of rings for Honda engines (70CC, 90CC, CRF70F, XL70, XR70, C70, CT70, ATC70, CL70) as well as other transport tribotechnical units was investigated. Due to the present ecological situation in the world, new environmentally friendly lubricating fluids for nitrogen steels’ tribotechnical units and surface treatments have been proposed. The results of tribotechnical tests are presented in the form of diagrams, graphs and step polynomials obtained by mathematically describing the changes in wear intensity when the load changes for different lubricating fluids. Friction pairs were compared with ShellHF-E 46 (synthetic lubricating fluid), ShellHF-R (biological origin) and lubricating and cooling liquids with 1%, 3% and 5% vegetable oil concentrations. In tribocoupling it was found that hydrogen diffuses into the metal because the tribodestruction of lubricating coolants plays an active role in the destruction of friction surfaces.

“…Nevertheless, a significant concern regarding laser cladding coatings is the non-uniform dispersion of reinforcements and the occurrence of fractures, both of which have a substantial impact on the qualities of the coating. Novel techniques employing optimized laser processing parameters and powdered alloy components have been devised to tackle this issue [ 1 , 2 , 3 , 4 ]. Preheating and post-heating are techniques employed to produce crack-free coatings in laser cladding.…”

The design of the resonant ultrasonic vibration-assisted laser cladding (R-UVALC) setup involved employing finite element analysis (FEA) to simulate the ultrasonic transducer, horn, and workpiece in a resonance state. The impact of R-UVALC on AlCrFeMnNi high-entropy alloys was assessed using various ultrasonic vibration amplitudes of 0, 5, 10, and 15 µm, with a constant frequency of 20 kHz. Ultrasonic vibrations reduced pores and cracks and increased the clad breadth, melt pool wetting angle, and laser-clad layer consistency. The columnar elongated grains in proximity to the substrate surface underwent a size reduction and transformed into grains with a more equiaxed shape with the utilization of ultrasonic vibrations at an amplitude of 5 µm. Laser cladding performed without ultrasonic vibrations yields two phases: face-centered cubic (FCC) and body-centered cubic (BCC). However, when the coating is exposed to ultrasonic vibrations with an amplitude of 5 µm, it forms a solitary body-centered cubic (BCC) phase. The microhardness tripled compared to the substrate, and the most significant microhardness value was achieved at 5 µm of ultrasonic vibration. The friction coefficient was assessed at an ambient temperature, revealing that an ultrasonic amplitude yields the lowest friction coefficient, demonstrating the excellent wear resistance properties of the coating. The analysis of the 3D surface profile of the wear indicates that the use of ultrasonic aid with a 5 µm amplitude leads to reduced depth of scars, and the primary wear mechanism observed is abrasive and oxidative wear with fewer grooves and debris. In addition, XPS analysis revealed the presence of metal components in an oxidized condition, suggesting that the wear process is oxidative in nature. Integrating the R-UVALC setup into a resonance state can significantly enhance the efficiency of the laser cladding process in the laser cladding field.
