Preventing Base Material Etching while Chrome Plating Aluminum Parts
A major supplier to the aerospace industry was in need of both chrome plating and nickel/chrome plating for turbine engine parts
made from aluminum. It was desirable to complete all machining operations prior to plating and Greystone was asked to prevent
base material etching and maintain all critical dimensions of the finished part during the plating process.
Many aluminum aircraft parts such as Yokes, Actuator Housings, and large Ball Bearings require chrome or nickel/chrome plating
for wear and corrosion protection. Most often these parts require selective plating coverage, which is to say they are not plated all
over but in particular areas such as only the ID of a housing or only an OD journal at a bearing location. Since aluminum is
chemically attacked by mostly all of the cleaning, activation and plating chemicals, the frequent result is a part which becomes
etched in areas that do not receive plating coverage.
Greystone engineers developed several methods to protect non-plate surfaces from coming in contact with the process chemicals
that etch the aluminum base material and cause stock removal. In many cases specialized hard tooling is designed and
manufactured by the Greystone team to have a custom fit for each part number and completely seal the part so that plating
solutions contact only the area which requires plating coverage. Additionally, Greystone engineers worked with manufacturers of
masking materials and tapes to formulate a special blend of material which can be applied to any aluminum part and completely
seal the base material from exposure to the process chemicals which lead to etching.
Greystone innovations in tooling design and a partnership with masking suppliers resulted in the development of a proprietary
process to prevent base material etching and stock removal while plating parts made from aluminum. With Greystone's ability to
protect all non-plated surfaces and maintain critical dimensions throughout the plating process, our customers benefit from higher
yields and reduced operating costs by finishing all machining operations prior to plate.
