Abstract
The results of a set of experimental studies of the properties of epoxy–sand composites used to repair parts of road-building machines are presented. The effect of the pretreatment of the particulate filler on the properties and structure of the composite was evaluated. The stability of the epoxy–sand composites in a harsh environment (deicing agent) was studied. The friction coefficients of the epoxy–sand composites were determined. It was found that a decrease in the filler concentration provides better resistance of the epoxy–sand composites to harsh environments and the best wear resistance.
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.
