Composites

Composites are made by powder “spheroidizing” in a specialist furnace with a controlled atmosphere. They are intended for detonation (Class “M”), plasma spraying and surfacing (classes “C” and “K”) of wear-resistant coatings for machine parts and mechanisms operating in conditions of fretting corrosion , abrasive wear, under normal and elevated temperatures.

M – small (0-63 microns)
С – average (63-160 microns)
K – large (160-280 microns)

The letters in the marking of the composite mean:

“CP”  –  a composite powder
“WC”  –  tungsten carbide
“Co” –  cobalt
“CrC” – chromium carbide
“N” – nickel
