Electroless nickel-boron plating developed as a variant of the similar nickel-phosphorus process, discovered accidentally by Charles Adolphe Wurtz in 1844. [2]In 1969, Harold Edward Bellis from DuPont filed a patent for a general class of electroless plating processes using sodium borohydride, dimethylamine borane, or sodium hypophosphite, in the presence of thallium salts, thus producing a ...
Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [3] To clean and protect the part during the plating process, a combination of heat treating, cleaning, masking, pickling, and etching may be used. [1]
Adams Plating, [1] also known as Adam's Plating, [2] is a 1-acre (0.40-hectare) [3] Superfund site in Lansing Charter Township [4] near Lansing, Michigan. Prior to 1964, a dry cleaning business was located at the site, and stored dry cleaning fluid there in an underground storage tank, which was removed in the 1950s.
In response, Erie Plating Company issued the following statement: In view of the adverse court decision metal finishers throughout the state are now liable for Use Tax dating back to September 1, 1953 plus a 25% penalty plus interest at 6%. What this means to the metal finishing industry in Pennsylvania is tragic to contemplate.
Before plating, the surface of the material must be thoroughly cleaned. Unwanted solids left on the surface cause poor plating. Cleaning is usually achieved by a series of chemical baths, including non-polar solvents to remove oils and greases, as well as acids and alkalis to remove oxides, insoluble organics, and other surface contaminants.
Mechanical plating, also known as peen plating, mechanical deposition, or impact plating, is a plating process that imparts the coating by cold welding fine metal particles to a workpiece. Mechanical galvanization is the same process, but applies to coatings that are thicker than 0.001 in (0.025 mm). [ 1 ]

There are several types of gold plating used in the electronics industry: [3] Soft, pure gold plating is used in the semiconductor industry. The gold layer is easily soldered and wire bonded. Its Knoop hardness ranges between 60 and 85. The plating baths have to be kept free of contamination. Soft, pure gold is deposited from special electrolytes.
