A gear manufacturer and supplier to one of the largest aircraft engine manufacturers requested a partnership with Greystone to
develop a reliable and repeatable method to selectively electroless nickel plate a gear shaft while masking to protect black oxide
coating in certain areas of the part.
Masking parts for the electroless nickel process is challenging due to the high operating temperature of the EN solution, which
typically runs at 200F. These high temperatures preclude the use of waxes and degrade the adhesive properties of most plating
tapes, rendering them useless. The nature of black oxide, and several other coating, is that it is easily attacked and stripped by the
chemicals in the plating line. This increases the degree of difficulty because the masking not only must prevent the electroless
nickel from depositing beyond the plate areas, but also prevent the pre-plate activation acids and plating solutions from seeping
behind the masks and attacking the black-ox.
Until this point in time, Greystone had over ten years experience with EN plating - both rack and barrel - high volume steel parts for
the automotive industry and additional experience with complex parts of various material alloys for a variety of applications, but
protecting a coating such as black oxide throughout the process was a new challenge. With a seventy-five year history of masking
and selective plating both chromium and electrolytic nickel, the Greystone Team of engineers and senior platers worked to develop
materials and perfect new techniques.
Greystone developed masking techniques with the ability to stand up to the high operating temperatures of the electroless nickel
solution and protect black oxide coated surfaces from being attacked by the cleaning and activation chemicals in the plating line.
With this completed, the team perfected application methods to reduce set-up time and reduce costs. The end result is a robust
process which yields a part completely protected by electroless nickel and black oxide, with no exposed base material.
