Preparation of various layered composites with wavy ribbon-like microstructure: (Ca3(PO4)2/ZrO2, Al2(TiO3)3/mullite, Al2O3/Ni, BaTiO3/Ni, etc.) by repeated folding and rolling of laminates of parrafin-based pastes and subsequential sintering. Goal: improvement of mechanical/electrical characteristics in comparison to particulate composites.
Study of the hydrolysis of various powder, such as AlN. Preparation of nano-structure ceramic layers (Al2O3, TiO2, SiO2, Ca3(PO3)2, hydroxy-apathite, etc.) on ceramic or metal substrates. Goal: applicability of such layers in medicine and engineering.
Dental ZrO2 ceramics: pre-clinical testing of prototype dental posts with a core for fixing the prosthetic crown – sand blasting, diamond grinding and fatique. Goal: improvement of the strength and fatique resistance.
Study of the origin of tunneling cracks and increasing of the bending strength of homogeneous and layered particulate Al2O3/Al2O3-ZrO2 composites, fabricated by slip-casting method. Connection: European project »Increasing the performance of total replacement prosthesis through functionally graded material innovation and design«.
- Research of the C/C composite with the surface protected by the SiC layer. Goal: the use of such composite for the production of braking discs for sports motorcycles, sports cars and aeroplanes. Development of multilayered SiC composite for antiballistic protection.
Research of very hard composite materials on the basis of AlMgB14-xTiB2 (x = 0,05-0,3). Synthesis of this compound by reaction sintering of the following elements and compounds: B, Al, Mg, TiB2, AlB12, MgB2.
- Application and development projects in collaboration with industry:
- AET, Tolmin: improvement of the wear resistance and cost reduction of the ceramics fabrication; development of the ceramic composites for the production of a new generation of glow plugs for Diesel engines
- MS Production, Bled: prototype ceramic braking discs with low thermal conductivity and good resistance to thermal shocks
