HARD-SURFACING

What is it?

Hard-surfacing is the application of a layer of wear-resistant alloy to a part for the purpose of extending the machine’s service life. This can be performed on worn parts to replace metal lost through wear and on new parts when wear is anticipated.

What is the benefit?

Each year, millions of metal machinery parts are protected and restored with COLMONOY® nickel-based and WALLEX™ cobalt-based Hard-Surfacing Alloys and thermal spray systems.

Parts protected with Wall Colmonoy’s Hard-Surfacing Alloys – last significantly longer than unprotected parts.

This means:

  • Fewer replacement parts needed
  • Less labor required to install them
  • Minimizes down-time

Galling, Abrasion, Corrosion, and Erosion

Application methods

The alloys are applied in a wide range of proven hard-surfacing and thermal spraying techniques, including PTA, HVOF, Spray & Powder welding, and Laser Cladding.

In fabricating new parts, inexpensive base metals may be used because our COLMONOY®, COLFEROLOY®, and WALLEX™ coatings withstand wear. To suit different application methods, our Hard-Surfacing Alloys are available as powder, rods, wires and castings.
