abstract = {Thermodynamic analysis was carried out to predict the phase
composition of a perhydridopolysilazane-type polymer derived
ceramic coating on Mo5SiB2 matrix particles after heat
treatment. The most probable chemical reactions between
these constituents and resulting phases were calculated. The
feasibility of PHPS/Mo5SiB2 chemical reactions was proved
experimentally. An amorphous SiOxNy phase and free Si were
found by X-ray diffraction analysis and Raman spectroscopy.
The presence of these two phases explain the improvement in
oxidation resistance of the Mo5SiB2 particles, which was
found to be as twice as high at 800 °C and 1100 °C in air,
compared to the unprotected plain Mo5SiB2 phase. The
oxidation of the free silicon provided by the PHPS
conversion was addressed as an oxygen trap.},
