Thermal spray coating is very widely used in various fields. It is technologically simple, compact, inexpensive, universal and mobile mode, which ensures a high process efficiency and good surface quality. In this paper, the examination of the possibilities to improve nickel base coating properties made by thermal spraying with vibromechanical treatment into the coating process. Studies at 30, 60, 90, 120, 150 Hz frequencies of introducing vibrations, and three different vibration amplitudes (different signal strength), the steel S235JR specimens was coated by thermal spraying. The nickel base powder PT-19N-01 for thermal spraying was used. The analysis of experimental results shows that, irrespective of signal strength and frequency, adhesion is low. Maximum adhesion value was achieved when the working frequency of vibromechanical treatment was 120 Hz, and the signal strength of 10 V. The lowest adhesion value was achieved when vibromechanical treatment frequency was 30 Hz, and the signal strength of 5 V.
