Effect of Functional Gas-Thermal Coatings on the Fatigue Strength of Structural Materials

The present study discusses the potential application of gas-thermal spraying technologies for the purpose of improving the fatigue strength of structural materials. A series of laboratory experiments employing multifactorial experimental design as a methodological framework are conducted. The fatigue strength of structural materials, including grade 45 steel and high-strength VCh 60-2 cast iron, is enhanced through the application of functional coatings formed by gas-thermal spraying a powder with the 95% EP-109 + 5% Al–Mg composition. The influence of the technological gas-thermal spraying conditions on the fatigue strength of the materials is mathematically modeled.

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.
