Σύνοψη

The primary objective of this project is to fabricate nanostructured coatings from amorphous powders by a thermal spray process, to prolong tool life and to explore other potential applications of such coatings in solar thermal and photovoltaic collectors and fuel cells.
Nanocoatings will enable increased thermal absorption, wear, heat transfer and corrosion resistance, fatigue strength and fracture toughness compared with conventionally manufactured coatings. High performance nanostructured coatings are projected to have a large economic impact in the energy, transportation and aerospace industries in the 21st century.
Advances in high performance materials for structural and thermal applications and the associated deposition methodologies will increasingly depend on our ability to control the size, distribution and morphology of their constituent phases at the submicrometer or nanometer level. Since capabilities for synthesising such nanostructured materials in bulk are becoming available, it is now possible to produce quantities of materials needed for prototype development and testing.
Nanostructured materials are a new class of synthetic materials with ultrafine microstructures, somewhat arbitrarily defined as structures smaller than 100 nm. These materials may be composed of metals, ceramics, polymers, and their composites. The materials can be in the form of powders, thin films, porous media, or dense structures.
The initiation of this project falls within the activities of the Nanomaterials Research Center (NRC), a newly established center at HTI, which serves as a bridge for technology transfer between HTI and the technology users (industry at large). The primary mission ofNRC is to develop new methods for the economical production of nanostructured metals, ceramics, and their composites.
Current research is focused on methods for the production of nanostructured powders, nanophase coatings (wear resistant surfaces, thermal barriers, solar cell fabrications, selective surfaces) and nanophase composites (gas turbine engines, bulletproofvests).
Under this center, two operating divisions have been established, each with its own application goal(s) and commercialisation strategy: (1) nanopowder synthesis, which is commercialising high rate production of non-agglomerated nanoparticles and (2) large area deposition of coatings. Both of the divisions focus on the commercialisation of advanced materials processes for enhanced mechanical and thermal properties.
