Laser Technologies of Gas Powder Surfacing and Heat Treatment of Drilling Equipment for Arctica Project Tasks

Abstract

Since nowadays the economy of the Russian Federation depends greatly on export of these mineral deposits, it is necessary to start development and exploitation of new deposits in a short space of time. Thereby, it is necessary to start rapidly development and sophistication of the technologies for reconditioning, repair and enhancement of performance characteristics of the drilling equipment used for extraction of mineral deposits, particularly, in the Arctic zone. The list of domestic manufacturers of drilling equipment is shown. Domestic laser installations for such technologies are described in the article.

Improving the durability of cultivator blades using one-sided gas-flame surfacing

“…The ability to increase resistance to wear processes allows to weld seam wear-resistant coatings on the friction surface of parts, which will reduce structural transformations that occur under mechanical and thermal influences on the surface of the cultivator blade [6]. Thus, the variety of existing technologies and methods to improve the durability of cultivator blades based on the factors of chemical, thermal and mechanical effects, which in turn allow the working bodies to comply with agrotechnical parameters [7,8,9,10]. Geothermal coating is one of the ways to strengthen the working bodies of tillage machines and create a surface layer that meets the increased operational requirements.…”
