“…They need to be reinforced with nanomaterials. It is known that the presence of alloying elements Energies 2021, 14, 4801 10 of 13 in the structure of cast iron and steel, such as manganese, chromium, tin, molybdenum, and some others, reduce hydrogen permeability and, consequently, hydrogen wear [3,37,38].…”

We describe the external and internal hydrogen iInteraction on contacting surfaces in the “cylinder–piston rings” friction coupling. Under the influence of high temperatures and pressure, the oil in the combustion chamber at a temperature up to 1473 K decomposes and forms small amounts of water. External hydrogen (H2) is subsequently formed. Hydrogen removal from the piston rings reduces the heterogeneity of the structure, residual stresses, and uneven physical and chemical properties of the near-surface layers, which reduces the stress concentration and, as a consequence, results in an improvement in the performance characteristics of the surface layers of the friction couple “cylinder-piston rings” of the spark ignition engine.

“…Investigation in the tribotechnical direction allows to assess the state and processes of destruction of materials in different operating conditions, including during setting [33][34][35][36]. Nitrogen steels are used to make rings for Honda 70CC, 90CC, CRF70F, XL70, XR70, C70, CT70, ATC70 and CL70 engines [37].…”

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.
