摘要：
A new aqueous sulfate trivalent chromium bath is described. The chromium bath contains formic acid and carbamide as complexing agents. Chromium was deposited at a temperature of 30 divided by 40 degrees C and a cathode current density of 10 divided by 25 A dm(-2). The bath allows obtaining thick (up to several hundred micrometers) hard chromium coatings with nanocrystalline structure. The electrodeposition rate reaches 0.8 divided by 0.9 mu m min(-1).
