Abstract

Data on the estimation and selection of working gases for powder plasma build-up welding are reported. Being selected appropriately, these gases protect molten metal against oxidation and stabilize arcing. The industrial use of plasma methods with a properly selected gas medium makes it possible to cover machine parts and equipment components by wear-resistant coatings. Mobile equipment for plasma build-up welding based on a KamAZ motor truck has been designed, as applied to which the thermophysical behavior of hot hydrocarbons has been considered. Recommendations for its use and operation control are given.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
