Nickel Plating Soluble
Bright Nickel
Anodes in nickel plating must be soluble into the bath. Pure nickel may be used with chloridecontaining 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 solution. Therefore ...

How to Select an Electroplated Finish?
Decorative Chrome Plating Nickelchrome, or coppernickelchrome, is a finish you see on many of your HarleyDavidsons and aluminum wheels on cars. There also is hard chrome plating that is used for wear resistance. We will not discuss this chrome plating process. Before decorative chrome plating became popular, people would nickel plate parts ...

The nickel plating process has been modified to produce molds for the blow molding, thermoforming, ... Nickel sulphate 1 is the principal ingredient; it is used as the main source of nickel ions because it is readily soluble (570 g/l at 50°C), relatively cheap, commercially available and is a source of uncomplexed nickel ions. However, it is known that a certain amount of ion association ...

What is a Nickel Plating?
· Electroless nickel plating is an autoalytic reaction used to deposit a coating of nickel on a substrate. Unlike electroplating, it is not necessary to pass an electric current through the solution to form a deposit. Electroless nickel plating has advantages over electroplating—free from fluxdensity and power supply issues, it provides an even deposit regardless of work piece geometry ...

MACDERMID ENTHONE NICKEL PLATING SOLUTIONS
Most nickel plating solutions, whether or not they contain addition agents, should be kept free from solid particles by means of adequate continuous filtration. Soluble impurities are removed by periodic batch purifiion. If continuous filtration is inadequate, occasional batch filtration may be required. When addition agents are present for the purpose of producing a bright deposit, the ...

29/09/2011 · 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. This will ...
