Abstract
A coated article and method of forming the same. The article is composed of a carbon body having a thermochemically deposited coating which renders the body resistant to oxidation at high temperatures. The coating is formed of a silicon alloy having a non-columnar grain distribution with substantially equiaxial grains of an average diameter of less than one micron. The amount of silicon in the coating is in excess of the alloy stoichiometry, producing infusion of silicon, with such at or above its melting temperature, into the cracked mosaic of the coating, to form an oxidative resistant glass filler.
