The monograph describes the basics of obtaining, properties, fields and efficiency of using composite diamond-containing materials, diamond-rubber, polymer and metal abrasive composites, abrasive-containing rolled tools with spraying and electrochemical deposition, for grinding and polishing, pastes and suspensions from STM. Methods of forming and properties of CTO powder coatings are given. Versions and physicality of combined methods of processing articles with cathodes on polycrystalline STM are considered. The economic problems of creating and applying STM are shown.
