Purpose of the development: Made with the proposed technology electric contact materials will be used as a high-resource welding electrodes, current collectors contact elements (in particular - high-speed trains), contacts, high-speed switches for switching high currents while minimizing electro wear of contact surfaces.

Recommended application field: Mechanical engineering, electrical engineering, instrumentation

Advantages over analogues: The economic effect of the introduction of the technology is implemented through a significant (2-5 times) increase in spark and arc conditions of stability of electrode materials, import-substitution of raw materials (in particular - tungsten), a significant (at times), reducing the cost of the electrodes in comparison with analogues made with silver, and tungsten-substituted copper contact materials.

The development stage readiness: The working documentation is developed

Technical and economic effect: The novelty of the proposed technological approach for dispersion of high-resistant composite electric-substituted materials based on copper, in contrast to known methods for obtaining substituted dispersed composites of this class is to use the method of internal oxidation, comprising administering to the initial batch of highly active additives, which are in the process of mechano-chemical synthesis and subsequent thermal treatment (heating for hot stamping) act as deoxidizing agents that not only effectively enhances the quality of interparticle contacts of metal particles of copper, but also represent the centers of formation of fine oxide particles of hardening.

Description of the development:
()
The proposed technology is based on the use of the effects of mechanochemical synthesis reaction (doping), the initial powder mixtures and special methods of hot forming of porous powder blanks with the implementation of schemes of landslide deformation, allowing for dispersion-hardened nanostructured material structure.
