cbn tin cbn tic composites chemical equilibria microstructure and Hardness Mechanical investigations
Diamond and Related Materials, 1999Co-Authors: Ewa Benko, Jan Skrzypek Stanislaw, Bogna Krolicka, Andrzej Wyczesany, Tery L BarrAbstract:Abstract This paper summarizes theoretical and experimental studies of cBN–TiN and cBN–TiC of cBN:TiN/TiC molar ratio 1:1 and 2:1. Theoretical calculations show that, at temperatures between 1000 and 1400°C, TiN reacts with BN forming one new phase, TiB2, and that TiC reacts with cBN forming two new phases, TiB2 and TiC0.8N0.2.. Experimental cBN–TiC/TiN composites were prepared by high pressure hot pressing and the samples were subsequently heat treated. After heat treatment, sinters of cBN–TiN/TiC were characterized using transmission electron microscopy and X-ray diffraction. The samples exhibited a dense polycrystalline structure, and a thin layer of fine TiB2 was visible at the BN–binder interface. It was found that Hardness decreased significantly after heat treatment.

Polyaryletherketone polymer nanocomposite engineered with nanolaminated Ti3SiC2 ceramic fillers
Materials & Design, 2014Co-Authors: K. V. Mahesh, S. Balanand, R. Raimond, A. Peer Mohamed, Solaiappan AnanthakumarAbstract:Thermal, Mechanical and tribological properties of a new ceramic–polymer nanocomposite in which polyaryletherketone (PAEK) polymer was reinforced with titanium silicon carbide (Ti3SiC2), a ceramic nanolaminate belonging to the MAX phase family (M is an early transition metal, A represents group IIIA or IVA element and X is either carbon and/or nitrogen) are reported for the first time. PAEK–Ti3SiC2 nanocomposites with varying volume fractions of Ti3SiC2 were processed by hot pressing. The effect of Ti3SiC2 on the thermal expansion, bulk Hardness, Mechanical strength, wear and friction properties was systematically analyzed and the results are discussed. The study confirms that the Ti3SiC2 controlled the high thermal expansion property of PAEK polymer. In addition to that, it enhanced the wear resistance and Mechanical strength of PAEK without affecting its inherent low-friction characteristics.
