THERMASIC – SILICON CARBIDE BASED POWDER FOR THERMAL SPRAY Seram Coatings´ product ThermaSiC enables SiC (Silicon Carbide) to be applied as a coating by thermal spraying for the first time. ThermaSiC provides superior coating performance in corrosive and abrasive environments as well as at high temperatures (up to 1500° C in air and 2400° C in inert atmosphere).
Abstract: Selective epitaxial growth (SEG) of cubic silicon carbide (3C-SiC) was carried out on patterned Si (100) substrates using SiO2 as a mask. The growth was performed by atmospheric pressure chemical vapour deposition in a resistance-heated furnace using hexamethyldisilane (HMDS) as the source.
Vacuum deposition is a generic term used to describe a type of surface engineering treatment used to deposit layers of material onto a substrate. The types of coatings include metals (e.g., cadmium, chromium, copper, nickel, titanium) and nonmetals (e.g., ceramic matrix composites of carbon/carbon, carbon/silicon carbide, etc.), deposited in thin layers (i.e. atom by atom or molecule by
At 1373 K to 1573K, the weight gain increased with increasing water vapor pressure. The oxidation rate was evaluated on the basis of the Ginstering-Brounshtein kinetic model. In this temperature region, the apparent activation energy for the oxidation was almost the same (139-191 kJmol -1 ) independent of the atmosphere, suggesting that the same oxidation process proceeds.
