In this paper, some physical and mechanical properties of the surface layer of widely used steel 65G in mechanical engineering and agriculture, subjected to plasma treatment. The research is aimed at increasing the service life of parts and friction units of machinery and equipment. It is shown that vibroplasma surface treatment with the use of metal-ceramic powders allows to increase the hardness of the surface layer by more than 3 times. The elemental composition and microstructure of the sample surface were studied. The microstructure of the base material of the coated samples corresponds to the structure of the reference sample. The microstructure of the reference sample corresponds to the microstructure of low-carbon (pre-eutectoid) steel after annealing. Grained ferrite-pearlite structure with a predominance of ferrite. In the process of vibro plasma treatment in the surface layer of the sample is formed of 3 zones: the zone of deposited metal-ceramic material, a hardened area of the surface layer mixed with elements of the base and filler material and heat affected zone.
