| Abstract: | The former art for electroplating flashlight switches includes ack plating first in a Zn-Cu alloy cyanide based bath and then in chromium plating bath, resulting in low efficiency and high waste-treatment cost. To eliminate such shortcomings, a new coating combination, nickel plus chromium-like S n-Co-Zn alloy deposit, which may be obtained from barrel plating process is suggested. Corrosion resistance and wear resistance of the combination coating are determined. Maintenance and trouble shooting of the Sn-Co-Zn plating bath are described. |
