Wear and Corrosion Alternatives - Chrome Plating

Chrome Plating Alternatives

Wear & Corrosion Links

There are several viable hard chrome plating alternatives, depending on the application and on whether it is an OEM part or a depot MRO component.

Thermal sprays – Primary replacement for most OEM and depot repair. Best performance. Limited for deep internal diameters and high strain fatigue applications.
Electro and electroless plates – Good for internals.
Vacuum coatings – OEM applications only. Not for rebuild.
Heat treatments – OEM applications only. Not for rebuild.
Laser and weld coatings – Localized repair.
