WEAR RESISTANT MATERIAL, EROSION AND CHEMICALLY RESISTANT, COATING, PROCESS TO PRODUCE A MATERIAL, PROCESS FOR DEPOSITION ON A SUBSTRATE OF A COATING, MATERIAL, PROCESS FOR DEPOSITION OF A MULTICRADED PRODUCT SUBSTRATE ON A PRODUCT SUBSTRATE TUNGSTEN CONNECTED WITH CARBON. A wear-resistant, erosion-resistant, chemically resistant carbon-containing tungsten-containing material, carbon being present in an amount of 0.01 wt.% To 0.97 wt.% Of the total weight, the material preferably comprising a carbon matrix. metallic tungsten with dispersed tungsten carbide nanoparticles having a particle size no larger than 50 nanometers, preferably no larger than 10 nanometers. The material is optionally also fluorine bonded, fluorine being present in an amount of 0.01 wt% to 0.4 wt% of the total weight. The material is extremely hard and strong.
