Korzhyk V. Scientific and technological principles of thermal spraying of amorfized coatings from metal alloys

The work involved is dedicated to investigation, development and application of the technology and metal materials for thermal spraying of coatings with an amorphous structure, improved physical-mechanical and special magnetic properties. The work relates to the development of a new area in the technology of thermal spraying, which is based on prediction of the heat transfer processes and structural state of the coatings depending upon the basic technological factors and the appropriate selection of optimal spraying compositions and process parameters to ensure maximum amorphization of the layers. Relationships of an increase in strength of adhesion of thermal spray coatings to the substrate, their fatigue strength, wear and corrosion resistance and improvement of magnetically soft characteristics with an increase in the amorphous phase content of the coatings have been established. Specialized consumables of the "AMOTEK" series and techniques are proposed for thermal spraying of the amorphized coating s, whose high efficiency has been scientifically grounded and proved in practice.
