Industrial Metal Finishing for Corrosion Control

Industrial Metal Finishing, which includes electro-deposition of metals and alloys, electroless plating, immersion plating, chemical and electropolishing of metals, anodizing etc. form a major component of surface engineering. Corrosion protection is one main reason for the existence of Industrial Metal finishing Although these processes began for decorative and aesthetic purposes,
their contribution to corrosion prevention and engineering applications, especially in electronics,aerospace, auto-motive and agriculture industries is markedly increasing. The evolution of industrial metal finishing from an art to a science has been a gradual process. The ABC of corro-sion protection, principle and mechanism, and the latest developments in terms of 6 Es (Environment-friendly, Econ-omical, Excellent. Energy -saving, Extremely fast, and Expertsystem ) have been briefly introduced. Relevant references have been cited for ease of access to the original and detailed literature.
