Nickel peeling from nickel is commonly caused by complete or partial loss of contact during nickel plating Total loss may result in an overall peeling condition Momentary or partial loss creates a bipolar condition in which current flow is from the lesser negative (poor or no contact) rack to the more negative (good contact) rack adjacent to it resulting in an anodic oxide film

Anodes in nickel plating must be soluble into the bath Pure nickel may be used with chloride-containing baths but when chlorides are not used as for example in sulfamate baths a special nickel anode metal must be used usually anode nickel containing sulfur to improve the anode solubility However the sulfur is as nickel sulfide NiS and does not dissolve into the

Nickel plating is common in jewelry making but often the nickel is plated with silver gold platinum or other noble metals Inexpensive jewelry simply stops at the nickel plate and thus nickel metal is in direct contact with the skin If the contact is long enough for sweat to react with the nickel the dissolved nickel can cause an allergic reaction

Nickel plating is similar to other electroplating processes that employ soluble metal anodes It requires the passage of direct current between two electrodes that are immersed in a conductive aqueous solution of nickel salts The flow of direct current causes one of the electrodes (the anode) to dissolve and the other electrode (the cathode) to become covered with nickel The nickel
