The technology for obtaining of porous powder materials with frame structure on the basis of spherical particles of titanium powder, using application of technological coatings of Тi (Si+Мо), (Si+С) or (W+С) was developed. Formation of the powder with the coating was conducted in molding die under the pressure below the flow limit (under 200 MPa). Reaction sintering in a vacuum furnace was carried out at the temperature of 900 оС with the exposure within 1 hour, which allowed receiving penetration factor over 39·10-13 m2 with the formation of powder porous materials with isotropic structure and increased properties.

It is suggested to use steel shot with the structure of tempered martensite for smelt modifying in the capacity of carrier-modifier. It was applied barrier nickel layer and then wolfram nano-coating (over 200 nm) along with protective cobalt layer, which prevents interreaction of oxygen with wolfram surface. Introduction of the modifier creates subcooling zone. When it interreacts with smelt the process of active mixing of the modifier with the smelt takes place. Subsequent crystallization carries involving large number of crystallization centers, which leads to reduction in the structure graininess and velocity and plasticity increase by 2-3 times.

Coating structure formation under magnetron spraying of titanium and carbon cathodes and combined cathodes, namely cobalt (EP 131) – nickel, tungsten – carbon have been investigated under conditions of carbide separate synthesis within the temperature range of 650–1200 °C. Usage of cobalt and nickel particles as matrix material leads to their rapid thermal expansion under heating during sintering process in the dilatometer. Subsequent plastic deformation of sintered samples provides obtaining a composite powder material that is a composite with framing structure of cobalt, titanium and tungsten carbides in the coatings.
