The development of CVD mullite coatings for high temperature corrosive applications

[摘要] Adherent crystalline mullite coatings have been chemically vapor deposited on SiC and Si(3)N(4)-based substrates to enhance its corrosional oxidation resistance. Thermodynamic and kinetic considerations have been utilized to produce mullite coatings with a variety of growth rates, compositions, and morphologies. The flexibility of processing can be exploited to produce coated ceramics with properties tailored to specific applications and varied corrosive environments. The coating and been tested in several corrosive environments including oxidation, jet burner exhaust, and Na(2)SO(4). (C) 1997 Elsevier Science S.A.
