Nickel-based powders

MARTEC atomized powders are Nickel alloy metal pellets.

Powder alloys are intended for hardfacing with spraying equipment: the powder is fed into the flame from a hopper attached to the torch. With this process the powder melts and binds together to the surface.

Nickel-based alloys contain usually Nickel, Chromium, Boron and Silicon.

Boron and Silicon are good fluxing elements.

The hardness of alloys depends on the Chromium-Boron-Silicon content.

Hardfacing with powders is suitable for:

  • repairing steel or cast iron parts,
  • protecting new parts and tools,
  • renovating worn tools.
