<p>A glassy carbon coated carbon foam material is formed by coating carbon foam with a glassy carbon layer. Carbon foam may be produced by carbonizing a phenolic or polyurethane foam at high temperatures in an inert atmosphere. The carbon foam is then machined to a desired shape and treated with a fine carbon or graphite powder to the surface. Subsequently a resin is applied to the surface of the carbon foam, and the coated carbon foam block is fired to carbonize the resin coating into a glassy carbon coating. The firing and coating are repeated until the desired coating thickness and surface properties are achieved.</p>
