Abstract
This paper is devoted to the high-effective process of surfacing by the indirect three-phase arc with covered electrodes. The share of the parent metal in the surfaced one does not exceed 10 % which is infeasible for one-arc surfacing.
Full Text
Operating conditions of technical systems, including the space machinery, require manufacturing of units and parts with specific properties of working surfaces, such as: heat resistance and thermal stability, wear resistance, corrosion resistance, etc. Thus, economical use of expensive materials is necessary. The problem is solved by using surfacing processes. However, widespread onearc method of surfacing with consumable electrodes has grave disadvantages such as low productivity and necessity of coating with four or five layers for required structure of surfaced metal. Application of alternating current in surfacing processes allows using simple and cheap power supplies that have higher efficiency in comparison with rectifiers.×
