    Abstract: A plating solution and method of forming such a solution for plating chromium and its alloys from Cr(III) is disclosed. The solution is an aqueous solution of a chromium(III) thiocyanate complex having at least a ligand other than water or thiocyanate in the inner coordination sphere.

    Abstract: According to the disclosure, electrochromic display apparatus is provided, comprising, an electrolyte containing an electrochromic material, a plurality of display electrodes in the electrolyte, the display electrodes being connected in at least one group to enable selection of display electrodes, means for selecting at least some display electrodes, means to effect deposition of a visible coating of colored species derived from the electrochromic material onto the selected display electrodes, and means to effect deposition of an invisible coating of the colored species onto all unselected display electrodes, whereby the potentials of selected and unselected display electrodes are equalized.

    Abstract: A very low concentration (below 0.03 M) trivalent chromium plating bath in which the source of chromium is an equilibrated aqueous solution of a chromium (III) - thiocyanate complex gives a deposit of unexpectedly light color. Such a bath is employed to produce thin overcoatings of light colored chromium for decorative applications. The bath and process is also used to plate the initial layer of a thick (greater than 5 micron) deposit for engineering applications, the major part of which is plated from a higher chromium concentration bath. Such thick deposits from a higher concentration bath are more cohesive and smoother when plated over an initial layer from the low concentration bath.
