Production of functional and composite nanostructured materials

Product

  1. Argon-arc welding nozzles based on Al2O3 (95 %).
  2. Sand-blaster nozzles based on B4C.
  3. Cutting-tool plates based on nanostructured materials.
  4. Medical restoration denture blanks based on zirconium dioxide (Y-TZP).
  5. Manufacture of Al2O3, B4C, zirconium-dioxide items to meet individual orders.

Description

Functional and composite materials are produced by the following methods:

  • vacuum quasi-isostatic-pressure sintering in electric fields;
  • hot isostatic pressing.

The manufacturing methods being in use allow to produce irregular-form sintered articles characterized by the uniform volume density and minimum concentration of macrodefects, enhance quality and service performance of the products due to generation of nanostructure in materials of products.
