LASER-ASSISTED TECHNOLOGIES

Laser–assisted direct manufacturing realised on the principle of selective laser sintering/melting of powder materials has great potentials to develop into the technology for serial manufacture of advanced components and parts due to some inherent capabilities, namely: ability to fabricate with unbounded geometric freedom, ability to produce shapes with micrometer scale precision, ability to process various powder materials (metals, alloys, ceramics, polymers), including the nanostructured and nanocomposite powders.
Laser cladding as a coating technique is currently paving the way to numerous industrial applications. New and novel coatings with revolutionary advanced performance get possible from research in nano- and micro-science and technology.

Technologies under scope

    • Laser-assisted Direct Manufacturing of functional 3D objects
    • Laser Cladding for surface treatment

Research topics and objectives

1. Laser-assisted Direct Manufacturing based on powder bed technique

    • 2. Laser-assisted Direct Manufacturing based on coaxial powder injection
  • Application of laser assisted technologies for fabrication of functionally graded coatings and objects for the international thermonuclear experimental reactor components

    • The actual interest in laser-assisted direct manufacturing consists in fabrication complex 3D objects with multi-material constitution. Divers and graded physical and chemical properties of different parts of the object enable enhanced and multi-functionality that make possible revolutionary advanced performance and numeous applications not available at present.
    Fabrication of objects with the engineered inner structure substituting bulk material in object body can yield lighweight components with desired mechanical and thermal conducting properties.
    Fabrication of complex micro components and miniaturised parts requires shape control with micrometer range resolution in details.
  • Direct metal deposition (DMD)


    • 3. Laser Cladding for surface treatment
  • Laser cladding of wear resistant metal matrix composite coatings

    • Laser cladding is a pathway to advanced 2D structures (thick coatings) with the properties and performance tailored to certain targeted applications. Special interest is in use of specific and unique properties of nano-structures, in particular, for improved tribologic materials. Fabrication of multi-material composite coatings can deliver highly innovative fuctionally graded and multi-functional coatings.
