Nickel composite powders for coatings

Application

Powders with exothermal reaction while flame spraying form on the steel substrate durable wear-resistant coatings based on the metallide Ni-Al. It can guarantee stated thermal effect and good fluidity through the holes sized 1.7—2.5 mm.

Spheres of application: CP-Al5-Ni and CP-Al10-Ni – as substrate material and for restoration of dimensions. Powders based on self-fluxing alloys are used for production of abrasion-resistant coatings combined with anticorrosive properties.

Powders are widely used for restoration and hardening of arbor slots, components of vehicles, seaborne machinery etc.

Method of coating deposition: flame spraying without flowing.
