    Abstract

    Black chromium deposits obtained from NAL black chromium13; bath (patented) are characterised by X-ray diffraction, SEM and TEM. These studies reveal that good quality black chromium deposits are obtained from this bath even at low current density and at relatively higher temperatures. This bath has good covering power on copper also. Based on the detailed study13; of chemical and phase compositions it is concluded that the coating is a composite containing chromium particles in amorphous Cr2O3 Matrix.
