| Summary: | Electrodeposition of nickel has been investigated intensely during the past decades in relation to its particular mechanical properties and numerous applications in industry. Electroplating of nickel coatings is frequently used for corrosion protection of stainless steel, also nickel electroplating plate is one of the protective-decorative electrodeposited metallic coating for stainless steel. Usually the electroplating process of nickel over stainless steel is done by common methods needed to some pretreatments such as preparation of surface, activating of the surface, striking a thin layer of nickel on the surface. In these methods there are some problems including: Poor level of Adhesion. Peeling off, Sometimes even after following all the proper pre-plating treatment the adhesion is also poor. Another problem is that a strike deposits usually very thin and examination of the strike layer may not show any signs of pitting and roughness. Because of these problems the nickel layer can not stick to stainless steel properly and it can peel off from the surface. In this study high speed electroplating will be applied to solve the problems and without any preparation the nickel will deposited on stainless steel. |
