Sintered SiC is a self-bonded material containing a sintering aid (typically Boron) of less than 1% by weight. CALSIC S is a fine-grained material with a typical grain size of < 5 microns exhibiting:
25/8/2012· Abstract. Coatings containing up to 66 vol.% of silicon carbide were deposited by plasma spray. Potential appliions can be found in the protection of CMC (ceramic matrix composite) against wear and high temperature oxidation. It is well known that SiC cannot be deposited by thermal spray because it decomposes before melting.
