Abstract

The paper reviews the results of using the self-propagating high-temperature synthesis (SHS) powder technology to obtain various nanomaterials, which can be utilized for tribological purposes. Firstly, these are low-cost nanopowders of sulfides, oxides, nitrides, carbides, borides and metals, which can be used as solid lubricants and friction modifiers for liquid and semisolid lubricants. Secondly, these are solid compact nanostructured ceramic and composite materials for the production of tribological structures. This type of nanomaterials can be obtained either ex situ from SHS nanopowders by sintering or introducing into the melt or in situ in a single stage from initial powdered reagents by the methods of gasostatiс SHS technology, force SHS compaction, SHS casting, and SHS in the melt, which significantly simplifies and cheapens production of such materials. Thirdly, these are SHS materials for application of nanostructured coatings of different thickness with high wear resistance and low friction factor, such as nanostructured materials for surfacing and spraying, electro-spark alloying electrodes, multicomponent targets for magnetron sputtering and cathodes for vacuum arc evaporation, nanosized fillers for electrochemical and electroless chemical coatings.
