The present invention relates to a composition comprising —a specific binder containing at least one cocondensate based on at least one ω-glycidyloxyalkylalkoxysilane and a bis(alkoxyalkylsilyl)amine, —water, —alcohol in an amount of less than 3% by weight, based on the composition, —at least one addition selected from the group consisting of particulate metals, metal alloys and metal compounds and —optionally at least one additive, where the pH of the composition is from 1 to 14 and the dry residue of the binder is from 1 to 50% by weight, based on the binder used, a process for the production thereof and also the use thereof for coatings, in particular for the protection of metals against corrosion.

A sliding member includes, on a surface of a metal substrate, a surface-treated layer including a zinc-electroplated layer, a chemical conversion-treated layer, and a topcoat layer sequentially stacked on the metal substrate. The chemical conversion-treated layer includes chromium and oxygen. The topcoat layer includes at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin. A method of manufacturing the sliding member includes a step of forming, on a surface of the chemical conversion-treated layer, the topcoat layer including at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin.
