#1016 - Micro Finish Improvement/ Decorative

Industry:

Aerospace - Manufacturers of piston assemblies for the aircraft industry

Micro-Finish-Improvement

MFG/METHOD:

Drawn/Stamping

ALLOY:

347 stainless steel

PROBLEM:

This part is used as a flex coupling and has seal rings inserted inside. The part is copper plated to act as a mask prior to Malcomizing/heat treating. After Malcomizing, the ‘Sleeve’ is stripped of the copper plating by reverse electrolysis. This leaves a rough surface finish

SOLUTION:

The entire component was electropolished with specifications to remove a controlled amount of material to achieve the required surface finish. The ‘Sleeve’ is bright and has a uniform finish. We provide special handling, inspection and packaging.


Note to engineer:Most heat treating operations produce at the minimum, heat discoloration, and at worst, heavy scale. Electropolishing is often specified as a post-heat treating operation to remove surface contamination. However, proper handling and pre- heat treat operations can maximize end finish results. Please contact our technical representatives for further information.
