Functionally graded ceramic-metal composites. Novel hybrid ceramic-metal composites. Composites of the following systems: ceramic matrix Al₂O₃, ZrO₂, SiO₂ with Fe, Mo, W, Ni, Ti, Al. Biomometics, biogenic silica, diatoms, ancient pottery.

Subject of investigation

• ceramics, ceramic matrix composites, ceramic-metal composites, ceramic-intermetallic composites, functionally graded ceramic matrix composites. 

Experimental work is developing together with Faculty of Chemistry of Warsaw University of Technology (WUT), Group of Professor M. Szafran.
   

Main developing topics

• Ceramics and composites with ceramic matrix (Al2O3, ZrO2) with metals  (Ni, Mo, Fe, Cu, Ti inne ) and with intermetallic phase (NiAl);
• Functional graded composites (Al2O3-Ni) fabricated according to elaborated in Group method of fabrication (patent  „Sposób wytwarzania elementów kompozytowych z gradientem fazy metalicznej”, PL 234766, 2019) odlewania odśrodkowego mas lejnych jak również z udziałem pola magnetycznego;
• Hybrid composites fabricated with precomposite powder (NiAl-Al2O3).
    

Research offer

• Microstructure characterization, SEM analysis, density and porosity of sinters;
• Analysis of mechanical properties (hardness, fracture toughness, compression test, bend test, wear resistance tests.
    

Collaboration with domestic scientific institution

• Faculty of Mechanical Engineering, Military University of Technology (WAT) Warsaw
