CNT–PyC–SiC/SiC double-layer oxidation-protection coating on C/C composite

Oxidation protection of carbon/carbon composites by a novel SiC nanoribbon-reinforced SiC–Si ceramic coating

“…The good interfacial bonding can alleviate thermal stress between the coatings and C/C composites, which ultimately affects the oxidation resistant capacity of the coated C/C composites [19]. Table 1 presents a comparative study of the interfacial bonding strength between C/C composites and coatings.…”

A carbon nanotube–enhanced SiC coating for the oxidation protection of C/C composite materials

“…In our previous short report [11], it was known that the incorporation of CNTs in SiC coating improved the oxidation resistance and thermal shock resistance of the coating. In this paper, we reported in a detail the deposition process and microstructure of CNT-SiC coating and the mechanism of its oxidation resistance.…”

Microstructure, surface emissivity and ablation resistance of multilayer coating for lightweight and porous carbon–bonded carbon fiber composites

“…Additionally, the introduction of refractory ceramic (i.e., ZrB 2 , HfB 2 , ZrC, HfC, MoSi 2 ) has succeeded in improving both the M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 3 oxidation/ablation resistance of the coating [9][10][11]. To improve the thermal shock resistance and the toughness of ceramic coatings, an effective strategy is the introduction of a second phase, such as carbon nanotubes (CNTs) [12], SiC whiskers (SiCw) [13], SiC nanowires [14] and H f C nanowires [15], which can alleviate the thermal stress and suppress the cracks in the coating. So far, many methods have been explored for preparing protective coatings for dense C/C composites, such as plasma spray [16], chemical vapor deposition (CVD) [17] and pack cementation [18].…”
