Friction problem in nickel plating parts
I AM DEVELOPING A HINGE TYPE COMPONENT. THESE ARE TWO 1.5 MM THICK MILD STEEL BARREL NICKEL PLATED 11 X 90 MM STRIP PIECES. HAS A HOLE IN EACH STRIP END & BOTH ARE JOINED THROUGH A NICKEL PLATED RIVET. JOINT IS NEITHER VERY TIGHT NOR LOOSE SO THAT WE CAN MOVE THE ASSEMBLED PART. AFTER RIVETING WHEN WE START ROTATING' AFTER A FEW ROTATION IT GETS JAM DUE TO REMOVAL OF NICKEL & SCRATCHES IN THE AREA WHICH ARE FACING EACH OTHER. please TELL HOW WE CAN SOLVE THIS. AS WHEN I USE SOME OIL OR GREASE IN THAT AREA IT WORKS WELL. WILL I HAVE TO USE OIL & GREASE AS A MUST? OR IS THERE ANY OTHER WAY ALSO. please REPLY.

Plate at least one surface using electroless nickel phosphorus. Nickel against nickel will almost always gall. but electroless NiP does not gall. You could use ENP on both surfaces.

A. Nickel against nickel is like stainless steel, it will gall, IE: it will try to cold weld together. If there is a heavy load or if the load is mild, but, with a frequent motion, nickel is a poor choice. Lubrication will be required. You could try electroless nickel plating the smaller of the two parts and see if that will work.James Watts
