Purpose of the development: The Ukrainian Institute has developed a technology and equipment for hot stamping powders of carbide steels belonging to a group of high-alloy steels and alloys of tool and structural purpose for working in conditions of intense friction and wear.

Recommended application field: - metal-cutting tools - for finishing and semi-finishing of carbon and low-alloy steels, non-ferrous metals and cast iron with high cutting speeds; - industrial knives, including - bimetallic, with a cutting part made of carbide steels, and the body part - of structural steel; - tools for metal-free metalworking - working parts of drawing dies, dies, rolling rolls, die molds, etc .; - gauges, end measures of length, conductor bushings; - structural parts - work in conditions of intensive wear and tear; - surfacing materials for reinforcement of wear parts surfaces.

Advantages over analogues: Carbide steels manufactured by the developed method of powder metallurgy have such advantages: - TiC grains (titanium carbide) are marked with a higher hardness than other carbides; - relatively low specific gravity - 10-20% lower compared to steels and almost 50% - compared with carbide tungsten carbide hard alloys; - increased wear resistance in 3-10 times in comparison with tool steels; - sufficiently high strength, resistance to heat, corrosion and corrosive environments; - in the annealed condition they are subjected to mechanical treatment; - to achieve high hardness subjected to thermal treatment; - the coefficient of thermal expansion is 50-90% lower than that of tool steels; - decreased propensity to adhesion interaction; - the coefficient of friction in sliding over metallic materials is reduced.

The development stage readiness: Introduced in production

Description of the development:
()
Carbide - powder composite materials. Their structure consists of solid refractory dispersed carbide grains (titanium carbide, titanium boride, titanium carbonitride) evenly distributed in the matrix phase from carbonaceous or alloyed steel with a carbide content of 15 to 70%. Physicomechanical and operational properties of carbide steels: ability to be thermally and mechanically processed; application in the manufacture of instruments of complex shape; increased hardness and wear resistance; lower ductility and viscosity. Developer resources for project implementation: - technological and technical documentation; - technological instruction for the production of products from carbide steels; - design documentation; - working drawings for the die block for hot stamping of workpieces from carbide steels; - domestic raw materials for production: the developed technology is based on the use of almost 100% of domestic raw materials; - long-term scientific and practical experience; - scientific and technical team; - equipment. Developer suggestions for cooperation: - manufacturing of products from carbide steels to order; - introduction of carbide steels into production; - the deployment of mass production.
