Studying the Resonance Processes in the Surface Layers of Friction Pairs with Lubrication by Means of Molecular Dynamics

The article investigates the resonances of diffusion processes using molecular dynamics method (MD) for heat-resistant steel carbonitriding. For this purpose, three types of resonances processes are used, different in terms of influence of thermal shock (TS) in the surface layers of heat-resistant steel with carbonitriding coating. The first type is nonlinear (cubic) resonance based on the frequencies of atomic fluctuations, ω0 in crystal lattice α-Fe and frequency under force of TS, ω. The second type is associated with resonance harmonics ω(i) force of TS and spectrum of atomic fluctuations in the lattice. The third type is related to the damping law of attenuation resonance processes in the depth of the surface. The article explores the first type of resonance processes. The result of resonance process conduction in the surface layer occurring to phase structural transformation reduces the formation of secondary structures, which determine the performance properties of the friction pairs.
