Double layer oxidation resistant coating for carbon fiber reinforced silicon carbide matrix composites

Recent progress on synthesis, multi-scale structure, and properties of Y–Si–O oxides

“…Although a number of experiments have been carried out on coating X2-Y 2 SiO 5 on C/C composites, [82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99] systematic work has seldom been conducted on the thermal and mechanical properties of Y 2 SiO 5 .…”

“…56,[82][83][84][85][86][87][88] The slurries for slip coating or dip coating usually consist of a Y 2 O 3 zSiO 2 starting powder mixture, synthesised Y 2 SiO 5 , Y 2 Si 2 O 7 , and their composites, or sol-gel precursors. For dip coating, excellent slurry fluidity is necessary to ensure homogeneous coating.…”

Oxidation and erosion resistant property of SiC/Si–Mo–Cr/MoSi2 multi-layer coated C/C composites

“…Preparing multi-layer oxidation resistance coating is an effective method for protecting C/C composites at hightemperature [8][9][10][11].Due to its good compatibility with C/C composites, SiC ceramic coating was widely used as internal transition layer in the coating system to protect C/C composites [12,13]. However, owing to the rapid vaporation of SiO 2 at high temperature, the oxidation resistance of SiC coated C/C composites is limited [14].…”

Concentration and Cyrstalline Phase Effects on the Spectroscopic Properties of Sol-Gel Synthesized Er³⁺:Y₂Si₂O₇ Nanopowders

“…Yttrium silicates (Y2SiO5 and Y2Si2O7) are promising materials due to the electrical, magnetic and optical properties in the fields of photonics [1][2][3][4][5]. They are also ideal candidates for environmental barrier coating (EBC) and dental applications due to their excellent high temperature properties [6][7][8][9][10].…”
