description: This research paper presents the results of studies aimed at a reasonable selection of technological parameters of argon-arc surfacing of a wear-resistant cobalt-based coating for Nuclear Power Station equipment that provide the required hardness and quality of the deposited metal. A detailed analysis of materials and methods of deposition is carried out. A study of the influence of technological parameters of surfacing on the shape and geometrical dimensions of deposited rollers was carried out, and thermal cycles of various surfacing modes were measured. Researches were made of the influence of technological parameters of surfacing on the hardness of surfaced rollers, and the resulting structure was evaluated. The prospects of further research on this topic are determined.
The result of the work is the selection of the optimal mode of argon-arc surfacing of a wear-resistant coating based on cobalt, providing the required hardness and quality of the deposited metal.
The work was carried out at the scientific and technical base of the NRC "Kurchatov Institute" - CRISM "Prometey".
