Purpose of the development: Designed to protect the surface of parts of machines, equipment and tools. There are "know-how".

Recommended application field: Mechanical engineering, wood industry, metallurgy, production of fire-resistant, oil industry, as well as in the repair and tool manufacturing companies in other industries.

Technical characteristic: - Hardness of 12-20 GPa, depending on the grade of steel, the type of coverage and operating conditions; - Wear resistance higher by 2-10 times in comparison with traditional tempering steel and in contact with the non-metallic materials (rubber, wood, plastic, ceramic) 15 times; - High corrosion resistance for CO environments, sulfuric acid and nitric acid environments; - Friction coefficient lower by 30% compared to the conventionally used methods of heat treatment at higher sliding speeds of 2 m / s; - High strength properties (7-10 GPa) zone located under boride needles to a depth of 800 microns. This creates a smooth transition from the surface microhardness in the middle part to prevent chipping or punching boride layer due to the difference in the microhardness of the diffusion layer and the base material part in the operation of the product reinforced with high specific loads; - High adhesion, characteristic diffusion coatings obtained by diffusion of reactive; - Heat resistance of 820-830 C in an oxidized atmosphere and 500 C. - in heavy abrasion for a long time; - Microhardness boride coating is higher than that of coatings produced by other methods of chemical-thermal treatment: cemented - 7.5-9.0 GPa; nitrided - 8,0-11,0 GPa; chrome - 9.2 - 10.0 GPa; borated - 12,0-2- 0 GPa; - The work of destruction - 100-120 J / kg; - Fracture toughness factor: phase FeB - 1,12-1,40 MPa; Phase Fe2B - 2,5-2,9 MPa; Modified alloying elements phase Fe2B - 3,6- 3,9 MPa.

Advantages over analogues: Improved specifications reinforcing parts coatings in comparison with coatings obtained by conventional methods.

The development stage readiness: Introduced in production

Description of the development:
()
Boriding process provides formation on the substrate or single-phase boride layer of high hardness, which increases wear resistance under dry friction and friction in the medium abrasive containing alumina, aluminosilicates, silica, metal oxides, and also improves heat resistance and corrosion resistance in corrosive environments. A film thickness of 50-250 microns for low, medium, high carbon steel, as well as low- and srednelegirovannoj steel. Increasing the size of the linear part is 30% of the total thickness of the boride layer. Boriding process is finishing operation for hardening of parts made with a surface roughness of not less than Rz1,67. Ensuring the creation of a uniform, continuous layer of variable thickness. Reinforcing parts of different configurations, it is possible to protect portions of the surface not to be boronized. There are "know-how".
