popup.description1
Determination of the influence of laser beam power on phase-structural transformations in the surface layer of gray cast iron; determination of the influence of the thickness of the pulse plasma coating applied to gray cast iron on the hardness and wear resistance of the specified alloy

Phase-structural transformation processes and wear resistance in coatings and surface carburized layers of biomedical alloy, treated with high-energy sources, including the use of pulsed plasma and laser beam.
The purpose of the work is to determination of the impact of post-plasma treatment and wear conditions on the abrasive wear resistance of pulsed plasma coatings; determination of the effect of combined treatment (carburizing + laser processing) on the phase-structural state and mechanical properties of biomedical titanium alloy.
Research methods: optical and electron microscopy, energy-dispersive spectroscopy, microhardness measurement, X-ray diffraction studies, and tribological testing. The study describes the microstructure, phase state, and tribological characteristics of coatings applied using pulsed plasma, the impact of post-plasma heat treatment, and the counter body material on the abrasive wear resistance of mono- and multilayer coatings. The phase-structural state and hardness of the biomedical titanium alloy, manufactured using LPBF printing, subjected to carburizing and subsequent laser treatment, were determined.
