Cobalt alloys for coatings
Cobalt alloyed powders are used in hardfacing technologies and in restoring machine components and equipment that operates in aggresive environments, abrasion and high temperature. Plasma coatings of cobalt alloys provide the surface with resistance to corrosion, erosion, and abrasive wear and maintain a sufficiently high hardness up to temperatures as high as 800°C.

The powders are applied to components of valves, valve seats, rotors, shafts, bearings in pumping devices in the oil & gas industry, parts of grinding machines, mixers, moulds, and, in drilling technology, to components of drill bits (3V16K powder), etc
Powders are produced by gas spraying (the particles are spherical).
Particle size (base grains), microns: -40 (45), -50, less than 100, 40-100, 45-106, 63-200 (160), 80-160, 160-280, 160-400, 280-400 et al.
The hardness of coatings depends on the manner in which the coatings are sprayed and deposited. The hardness of coatings obtained using the plasma spraying method, following thermal treatment, ranges from 42-50 HRC.
