We study the solubility of the nanopowders of borides and carbides of metals of groups IV–VIB and a nanopowder of silicon carbide in standard nickel-plating electrolytes. As objects of investigation, we use nanopowders containing 91.8–97.6% of the main phase with average particle sizes of 32–78 nm. Their corrosion resistances are evaluated as functions of the acidity of electrolyte, temperature, and duration of interaction. It is discovered that the corrosion resistances of boride and carbide nanopowders in solutions of electrolytes are similar within each group of compounds and characterized by an unbounded period of holding in alkaline media. A silicon carbide nanopowder, which is stable in solutions of any pH value, proves to be an exception.
