description: The topic of the final qualification work is "Development of plasma technology for the formation of erosion-resistant coatings for arc-extinguishing contacts of air circuit breakers." This work is devoted to studying the effect of the coating material on the erosion resistance and operational characteristics of the arcing contact. The purpose of the master's final qualification work is the development of a plasma technology for the formation of erosion-resistant coatings for arc-extinguishing contacts, followed by confirmation or refutation of the feasibility of its use in the apparatus-building branch of the electrical industry. The work was carried out on the basis of the "ETU" laboratory of the St. Petersburg Polytechnic University. Methods of synthesis, analysis, experiment were used. As a result of modeling in the "Comsol Multiphysics" software environment, the process of initiation and burning of an electric arc in the space of the arc-extinguishing chamber, the prospects of using arc-extinguishing contacts with erosion-resistant coatings based on copper and graphite deposited on their surface were revealed. A coating technology has been developed. The feasibility of using the developed technology in apparatus construction has been investigated and confirmed.
