Latest Patents

Davidovich's latest patents include a carbon-graphite material for brushes of electric machines and a method for manufacturing carbon-graphite brushes. The first patent describes a carbon-graphite material that incorporates ultraphosphates of metals sealed by film-forming polymers. This innovative material is treated with a mixture of metal chloride and orthophosphoric acid, followed by heat treatment to ensure the ultraphosphates are evenly distributed. The resulting material exhibits improved contact characteristics and high wear resistance, making it suitable for a wide range of operational conditions.

The second patent focuses on carbon-graphite brushes designed for heavy-current electrical engineering. These brushes are characterized by their high wear resistance and low adhesive capacity of the brush dust. They are intended for use in commutator machines under moderate to heavy commutation conditions, operating at temperatures between 200°C and 250°C. The manufacturing method involves impregnating the brushes with a melamine-glyptal resin and metal linoleate mixture, followed by heat treatment to achieve optimal performance.
