Modern industry imposes ever increasing requirements upon tools and
tool materials as to the provision for performance under the
conditions of high cutting speeds and dynamic loads as well as
under intensive thermal and chemical interactions with workpiece
materials. The industry demands a higher productivity in
combination with the accuracy of geometry and dimensions of
workpieces and quality of working surfaces of the machined pieces.
These requirements are best met by the tool superhard materials
(diamond and diamond-like cubic boron nitride). Ceramics based on
silicon carbide, aluminum and boron oxides as well as on titanium,
silicon and aluminum nitrides offer promise as tool materials.
Tungsten-containing cemented carbides are still considered as
suitable tool materials. Hi- hardness and high strength composites
based on the above materials fit all the requirements imposed by
machining jobs when manufacturing elements of machinery, in
particular those operating under the extreme conditions of high
temperatures and loads. These elements are produced of difficult--
machine high-alloy steels, nickel refractory alloys, high-tech
ceramics, materials with metallic and non-metallic coatings having
improved wear resistance, as well as of special polymeric and
glass-ceramic materials. Materials science at high pressure deals
with the use of high-pressure techniques for the development and
production of unique materials whose preparation at ambient
pressure is impossible (e. g. , diamond, cubic boron nitride, etc.
) or of materials with properties exceeding those of materials
produced at ambient pressure (e. g. , high-temperature
superconductors).
