SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Original results of studies of structure and properties of a nanostructured (nanocomposite) film and coating are presented. A classification of nanocrystalline films (3 groups) is presented. Effect of an ion bombardment in the process of deposition is considered. A nanocomposite coating (including multi-layered one), hard, and superhard one is considered. Their definition is presented and their thermal stability is considered. A whole class of super-hard composite materials featuring H ≥ 80GPa is described in detail. The super-hard nanocomposite is composed of a transition metal nanocrystal TiM (where M is Ti, Zr, Mo, Ta, etc.), which is surrounded by one mono-layer of an amorphous (or quasi-amorphous) system α-Si3N4, BN.
