In this paper we consider the possibility of ultrasonic surface treatment of steel machine parts before applying thermal coatings. It is proposed to use an ultrasonic treatment in a process for preparing surface coatings by thermal spray deposition. Analyzed and the possibility of the effective use of ultrasound during deposition. The proposed method greatly increases the adhesion characteristics of the composition “coating-base”, reduces the energy of the activation barrier, creates a favorable morphology of the surface under the coating. The method may be used as an alternative to abrasive machining, when it is necessary to exclude caricaturing and creating stress concentrators, e.g., sensing components for cyclic loading.
