Abstract
We have studied the effect of discharge pulse duration in the electrospark deposition process on the structure and properties of FeCrWMoCB metallic glass coatings. The coating thickness has been shown to rise from 19.1 to 39 μm with increasing pulse duration. The heat resistance of the coated samples over 100 h of testing at 700°C was 27 to 176 times that of the steel and it increased with increasing pulse duration. The hardness of the coatings ranged from 11.3 to 11.9 GPa. The coatings have been shown to reduce the friction coefficient and wear of the steel by a factor of up to 3.7 and improve its corrosion resistance.
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
