Dimensional repair coatings restore worn or damaged components to their original specifications. We rebuild surfaces with thermally sprayed metals using HVOF, HVAF, plasma, flame spray and twin-wire arc, often improving wear and corrosion resistance and extending component life.
Metals we use for restoration
- Nickel alloys: excellent corrosion resistance, good build-up capability and a machinable finish. Used to restore dimensions in corrosive environments.
- Stainless steel: strong corrosion resistance, high toughness and excellent build-up capacity. A cost-effective rebuild for corrosive environments.
- Matching alloys: virtually any alloy the base metal is made of.
Repair instead of replace
Parts that would otherwise be scrapped can be reclaimed and brought back to specification again and again, which adds up to considerable savings over time. Our coatings often outperform the original part.
We can also apply a wear-resistant top coat over the restorative metal layer: a ceramic, such as alumina or chrome oxide, or a carbide, such as tungsten carbide or chromium carbide.
Finished to print
Repaired parts are finished in our own grinding, CNC machining and lapping shop, so they go back into service at their original tolerances.
