“…In contrast, the large SiC particles are only slightly oxidized, as confirmed by EDS analysis (not shown). As reported in the literature [30,31], the oxidation rate of the carbide particles strongly depends on the particle size. Small carbide particles possess a large surface area and can be rapidly oxidized in a short time to form a continuous and uniform glass film covering the surface of the composites.…”

and SiO 2 , which covers the surface of the composites and retards the oxygen diffusion and the attack on the underlying C/C substrate. For SiC coated C/C composites, the large SiC particles formed on the surface of the composites are difficult to oxidize rapidly and so a continuous and dense SiO 2 layer cannot be formed in time to significantly hinder fast oxygen diffusion leading to the consequent severe oxidation of the C/C substrate.

“…Although these oxides are protective in static oxidation conditions, B-oxide melts below 600 ºC [21,22], which leads to its easy removal hindering the formation of a stable oxide layer over the surface. As the process requires some time, since temperatures are still low being oxidation rates low [10], the destruction of the growing oxide layers is relatively easy and the formation of a transfer layer is limited due to the dragging effect caused by the ball sliding and melted B-oxide.…”

In the present investigation the effect of the substrate dilution on room and high temperature (550 and 700 ºC) tribological behaviour of nickel based hardfaced coating deposited by plasma transferred arc onto a grey cast iron was investigated and compared to the uncoated grey cast iron. At room temperature, the wear loss of coatings was independent of the substrate dilution and similar to the grey cast iron. At high temperatures, coating produced with high dilution displayed the highest wear resistance between all the samples. This is attributed to the formation of a protective tribo-layer resulting from the agglomeration of a high amount of oxide debris due to its lower oxidation resistance when compared to the sample produced with low dilution.

“…Investigations on oxidation of B 4 C have been performed under different experimental conditions (including material composition, physical form of specimens, heat treatment atmosphere and temperature) in the past [14][15][16][17][18][19][20][21]. However, only a few studies are available on the oxidation behavior of chemical vapor deposition (CVD) B 4 C coatings.…”

Carbon-rich amorphous boron carbide (B x C) coatings were annealed at 400uC, 700uC, 1000uC and 1200uC for 2 h in air atmosphere. The microstructure and composition of the as-deposited and annealed coatings were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), micro-Raman spectroscopy and energy dispersive X-ray spectroscopy (EDS). All of the post-anneal characterizations demonstrated the ability of carbon-rich B x C coatings to protect the graphite substrate against oxidation. Different oxidation modes of the coatings were found at low temperature (400uC), moderate temperature (700uC) and high temperature (1000uC and 1200uC). Finally, the feasibility of the application of carbon-rich B x C instead of pyrolytic carbon (PyC) as a fiber/matrix interlayer in ceramics-matrix composites (CMCs) is discussed here.
