Chemical Vapor Deposition (CVD Coating) | Ultramet

Chemical Vapor Deposition. Chemical vapor deposition (CVD) results from the chemical reaction of gaseous precursor(s) at a heated substrate to yield a fully dense deposit. Ultramet uses CVD to apply refractory metals and ceramics as thin coatings on various substrates and to produce freestanding thick-walled structures.THE CHEMICAL VAPOUR DEPOSITION AND BURST TESTING,Silicon carbide has a low neutron absorption cross-section^1] and good stability under irradiation in the temperature range 250 - 700°C and at doses of up to at least 3 x 1020 n/cm2^2'3-'. Silicon carbide tubes can be fabricated by the chemical vapour deposition (CVD) process and retain their high strength at elevated temperatures.Simulations of Silicon Carbide Chemical Vapor Deposition,The work presented in this thesis focuses on computer simulations of chemical vapor deposition (CVD), especially silicon carbide epitaxial growth. It was carried out at the Materials Science Division at the Department of Physics and Measurement Technology at Linköping University, Sweden, during the period October 1998 – October 2002.
