Abstract

A β-SiC coating made by the method of mixing SiO2 with carbon and heating the mixture in vacuum wherein the carbon is oxidized to CO gas and reduces the SiO2 to SiO gas and reacting a carbon material, comprising stainless steel with a carbon coating, with the SiO gas at a temperature in the range of 1300 to 1600° C. resulting in a SiC coating on the stainless steel.
