Molybdenum and tungsten products for production of leucosapphires
POLEMA JSC is the leading global manufacturer of chromium, molybdenum, tungsten products, metal powders and composite materials.
Nickel composite powders for coatings
Application
Powders with exothermal reaction while flame spraying form on the steel a durable wear-resistant coatings based on the metallide Ni-Al. It can guarantee a stated thermal effect and a 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.
