A double layer nanostructure SiC coating for anti-oxidation protection of carbon/carbon composites prepared by chemical vapor reaction and chemical vapor deposition

A SiC-ZrB2-ZrC coating toughened by electrophoretically-deposited SiC nanowires to protect C/C composites against thermal shock and oxidation

“…However, the applications of C/C composites are limited by their poor oxidation resistance, which will be oxidized at a temperature as low as 450 • C [4]. SiC-based coating is considered as an effective way to solve this problem, owing to the formation of SiO 2 glassy film with low oxygen permeability at high temperatures [5,6]. In addition, it is also widely used as internal coating because of its good physical and chemical compatibility with C/C composites [7,8].…”

Effects of polymer derived SiC interphase on the properties of C/ZrC composites

“…At over 2000°C in air, the use of traditional C/C, C/silicon carbide (SiC) composites or other new materials is limited because of rapid oxidation and ablation [3][4][5]. ZrC, one of ultrahigh temperature ceramics (UHTCs), is of great interest for its high melting point (3400°C) and excellent ablation resistance [6].…”

Cryogenic friction-stir processing of ultrafine-grained Al–Mg–TiO2 nanocomposites

“…Various techniques have been developed to process UFG materials. In a "bottom-up" approach, bulk specimens are fabricated from nanoscale building blocks through inert gas condensation [11], electrodeposition [12], and chemical and physical deposition [13][14]. Another way to prepare UFG solids is to use coarse-grained materials and induce substantial grain refinement by severe plastic deformation (SPD) [2,15].…”
