英文摘要	Almost all of the currently achievable chromium coatings using Cr(III) electrolytes are amorphous. In this work, a crystalline chromium coating with an attractive appearance was produced on Cu substrates. This was achieved using direct current (DC) electrodepositing of a wholly environmentally acceptable sulfate Cr(III) electrolyte without a subsequent heat treatment. Structural characterization revealed that the crystalline chromium coating deposited at 5A/dm² from the electrolyte solution is composed of body-centered cubic (bcc) Cr crystals, which demonstrated significant preferred orientation and a size range of 50–60 nm.The results also show that, in general, the color and luster of the chromium coating are greatly affected by the current density employed, and the larger the current density is,the dimmer thecoating.
