Galling between Nickel finish and Stainless Steel
We are manufactures of electromechanical RF relays and we are experiencing gauling problems with our nickel plated Rockers and the Stainless Steel Pivot Pin. We routinely life cycle test our products. About 1/2 way thru our life test a brown dust is formed and the Rocker binds on the shaft. The Rocker is aluminum with .0004 inch thick electroless nickel and the Pin is .0625 diameter passivated stainless.
Please forward any suggestions or comments you may have.
Thank you,Bud Jones

Is the electroless nickel worn through on the aluminum part? If so consider increasing the thickness of the EN to .001in. If the EN is not worn through consider using an electroless nickel Teflon composite coating.Todd Osmolski
