An AlPO 4 oxidation-protective coating was successfully prepared on SiC pre-coated carbon/carbon composites (SiC–C/C) by pulse arc discharge deposition. The structure and oxidation resistance of the as-prepared AlPO 4 /SiC multilayer coatings were investigated. The results were confirmed by oxidation experiments performed at 1573 K, 1673 K and 1773 K, which demonstrated that the AlPO...
The properties of Ti–6Al–7Nb alloy oxidation in the temperature range from 500 to 800 °C, in various time periods between 20 min and 72 h, were examined. The rate of oxidation at temperatures of 600, 700 and 800 °C, determined on the basis of the weight gain, was described by a parabolic equation. The obtained oxidation activation energy value was 170 kJ/mol. In addition to oxidation kinetics, the...
The purpose of this study was to investigate the effects of vacuum heat treatments on microstructures, associated mechanical behavior and oxidation behavior of TiZrN films. The films with three Zr/(Zr + Ti) ratios of 0.3, 0.5 and 0.7 were prepared using a DC reactive unbalanced magnetron sputter system. The annealing temperatures ranged from 700 to 1000 °C. X-ray diffraction (XRD) and microstructural...
Hafnium-doped aluminide coating was deposited on Inconel 100 superalloy by the CVD method. The coating consists of two layers: the additive and the interdiffusion one. The coating was formed by the predominant outward diffusion of nickel from the substrate. The additive layer consists of the β-NiAl phase and the interdiffusion layer consists of the β-NiAl phase with M 6 C and M 23 ...
Large-area MoS 2 thin layers have been synthesized onto the SiO 2 /Si substrate by the thermolysis of (NH 4 ) 2 MoS 4 film. The structure and growth mechanism of MoS 2 thin layers have been investigated. The results reveal that MoO 3 can be easily formed during the growth process of MoS 2 film, which will dramatically degrade the quality...
