coatings serve the dual role of providing a bright decorative coating and imparting improved corrosion resistance or other functional properties. A further important use for electrodeposited nickel is. the application of electrodeposited coatings and by using modern methods of surface treatment and post heat-treatment (baking), the risk of hydrogen embrittlement cannot be completely eliminated.

Therefore, the application of a metallic File Size: KB. The metallic coatings produced by CVD process (e.g., chromium or nickel coatings) are very pure and flexible and deposited by approximate density of %. However, CVD is a more expensive process.
