Plasma Processing Department of Lithuanian Energy Institute are interested on plasma sprayed ceramics coatings (Al2O3, YSZ, etc.) and diamond-like coatings. Collaboration may cover such areas as:
- Microstructure and morphology of plasma sprayed films
- Relationships between mechanical and tribological properties of plasma sprayed coatings
- Optimisation plasma torch design and spray parameters for each coating material
- Evaluation of lifetime of plasma sprayed coatings
Experience of the department
From 2000 technologies for plasma modification of surfaces and plasma spray deposition of thin coatings with different mechanical and chemical properties are investigated and practiced.
We have experience of work in the following research and development areas:
- Investigation of interaction of plasma with dispersed materials
- Investigation of melting of high temperature oxide ceramics
- Deposition of thin and highly adhered ceramic coatings on surfaces from different materials for catalytic application
- Formation of coatings on construction materials to improve anticorrosion and tribological properties for bio application
The equipment of department
- atmospheric and reduced DC plasma torches (30–500 kW) and supplying equipment
- equipment for coating technology
- optical microscopy and scanning electron microscope JEOL JSM – 5600
- equipment for preparation and analysis of metallographic specimens
- X-ray diffraction
Also we have possibility to characterize obtained films using
- The Fourier transform infrared (Perkin Elmer) spectrometer (model Spectrum GX FT-IR)
- Conventional grating Raman spectrometer
Topics for collaboration
Hard ceramics films:
- Engineering of ceramic materials for biomedical devices
- Coating of metallic samples and investigation of plasma processing on the microstructure and properties of bioceramics
- Optimisation of the composition and microstructure of bioceramic coatings to yield improved properties
Diamond-like coatings:
Our researches may be concerned with production of the carbon nanostructures from hydrocarbon gases by plasma jet CVD technique at atmospheric or reduced (100 Pa) pressures. Experimental researches could be carried out to find the catalyst materials for production of carbon nanostructures. Possibility to synthesized carbon films from various hydrocarbon gases (methane, acetylene and etc.) and characterization the structure, bonding type, surface morphology of the carbon films by Raman spectrometer, X-ray diffraction, the Fourier transform infrared spectrometer, and scanning electron microscope.
Since 1965 the Plasma Processing Department has been working in the field of heat transfer of high temperature plasma flow physic, generated at atmospheric pressure by DC plasma torches. The research was carried out on gas dynamic and heat transfer of high temperature gas and plasma flows in nozzles of various shapes and size, in channels of different configuration, high temperature exchangers and free jets.
