Abstract—The possibilities of coating highly loaded aluminum alloy parts with refractory cast iron are considered. The problem of preserving the geometry of parts without thermal destruction due to their coating, which creates heat-protective properties on the product surface by erosion-chemical pulse hardening with cast iron electrodes, has been solved. The mechanism of forming heat-resistant joints of parts for assemblies with high wear resistance and a low coefficient of friction of movable structural elements, which are lightened by 20–25% compared to parts made of gray cast iron, is revealed. The use of a combined erosion-chemical method of hardening, manufacturing, and restoring the operational properties of cast iron parts made it possible to halve the labor costs and the cost of parts when processing products under field conditions using minimum technological equipment.
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.
