Amorphous and nanocrystalline chromium-carbon coatings have higher properties than standard galvanic chromium ones. However, data on these coatings and their heat-treatment regimes are quite scarce. The present paper concerns the structure, microhardness, ductility, adhesion strength, and resistance to overall and pitting corrosion of amorphous chromium-carbon coatings deposited galvanically by various regimes in an electrolyte based on chromic anhydride with an additive of formic acid.
