Corrosion resistant Nickel Alloy Coating

News: A new method of deposition of Nickel alloy coatings on high-performance materials in engineering applications can replace environmentally toxic chrome coatings. The coatings obtained are also highly corrosion-resistant and useful for the plastic ware. 

What is Chrome plating and issues associated with it?
• Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object.
• The chromed layer can be decorative, provide corrosion resistance, ease of cleaning, or increase surface hardness.
• However, Chromium contains Hexavalent chromium, which is a known carcinogen. The plating process uses lead, which can be absorbed through the skin and can cause liver, organ and brain damage. Cyanide is very toxic.
