Microstructure-controlled and fully-dense ZrB2 HfB2 composites were elaborated by Spark Plasma Sintering with two different amounts of SiC (20 30 vol%) added to improve their oxidation resistance using optimized sintering parameters. Oxidation several samples in air plasma conditions, at 1000 Pa total pressure from 1800 K up 2600 K, was carried out. The mass variation during duration 300 s on a...

There is a need for developing synthesis techniques that allow the growth of high-quality functional films at low substrate temperatures to minimize energy consumption and enable coating temperature-sensitive substrates. A typical shortcoming conventional low-temperature strategies insufficient atomic mobility, which leads porous microstructures with impurity incorporation due atmosphere exposu...
