Composite and functionally-graded target for PVD
Multicomponent thin films
Development and synthesis of advanced multicomponent, multiphase and
functionally-graded targets with high dense, uniform structure that exhibits
the required mechanical, thermal and electrical properties needed for
such technological materials. Our new functionally-graded materials
(FGM) meet the technological requirements concerning a high level
of toughness and thermoconductivity for targets

Application of PVD films
Various biomedical application (antibacterial coatings for packing and
storage of medical tools, deposition of coatings on medical instrument,
etc); depositions of hard, wear- and corrosion resistant coatings on the
surface of cutting tools and parts of machines and mechanisms; deposition
of thin films for various electronic, magnetic and optical applications
(semiconductor devices, lenses, etc.)
