Аннотация
High-temperature electrochemical synthesis and currentless transfer in molten salts were used to obtain coatings constituted by carbides of refractory metals (Mo2C, Cr7C3, NbC, and TaC). It was found that the Mo2C/Mo composite synthesized from a chloride-carbonate-molybdate melt has the highest catalytic activity. It was shown that the Mo2C catalytic coating preserves its properties for at least 5000 h of tests. The protective properties of refractory metal carbides of composition Cr7C3, NbC, and TaC significantly improve the corrosion resistance of steel articles in concentrated solutions and raise their wear resistance by an order of magnitude.
