Abstract

Electrodeposition is a process, which uses an electrical current to reduce cations of a desired material from a solution and coat that material as a thin film onto a conductive substrate surface. In this case, zinc cations will be reduced and coat the steel substrates acting as a sacrificial coating to provide corrosion resistance. Three widely used industrial zinc plating processes will be examined, including acid chloride, alkaline cyanide, and alkaline non-cyanide. These processes will be discussed in terms of throwing power, cathode efficiency, hydrogen embrittlement, deposition mechanisms and salt spray testing. After the zinc plating line is operational, training methods must be documented to adhere to ISO 9001 quality level.
