Abstract A comparative analysis of the physical and mechanical properties of coatings obtained using electric arc spraying and hypersonic metallization methods is made. Comparisons were carried out when applying the coatings of wire Sv-08G2S. It is shown that the coatings obtained by hypersonic metallization have 2–5 times higher density compared to coatings obtained by electric arc spraying, as well as superior adhesion strength by 1.5–2 times, microhardness by 1.2–1.5 times, oxidation resistance by 1.5–1.7 times. It is established that the use of hypersonic metallization for the recovery and hardening of machine parts with the use of wire Sv-08G2S is more preferable than the use of electric arc spraying.
