Alloying of Stacked Nickel/Zinc Films Through Heat Treatment

摘要

Environmental Regulation has become strict year by year and the substitutes for some harmful elements are required urgently in various areas. Alloy plating is one of the candidates as substitute. Nickel-Zinc Alloy Film has been well known for high corrosion resistance. However, the conventional alloy plating requires a certain combination of chemicals and it may lead to another environmental problems such as effluent. Therefore, we investigated another production process for the alloy film through the combination of heat treatment and multi-step plating (HSSL Process). The possibility of alloying was examined by X-ray analysis and SEM-EDX.
