【Abstract】 The effect of potassium iodate on chromium electrodeposition was studied in the paper. The stability of chromium plating solution which contains organic additives was improved by the addition of potassium iodate, and the cathodic current efficiency, the covering and throwing power of the solution were also improved with and without potassium iodate. It was found that potassium indate could not co-deposit with chromium by using the analysis method of X-ray photoelectron spectroscopy.更多还原
