ABSTRACT:
A coating composition containing 75-95% MgO, 2-10% B.sub.2 O.sub.3 and 0-15% C, which is effective in retarding oxidation of ferrous metal articles, especially at temperatures in excess of 2150.degree.F. Additional protection is achieved when about 11-17% TiO.sub.2 is substituted for about the same amount of MgO. The composition is admixed with a suitable vehicle and is applied to the metal surface in the form of a dispersion, suspension or as a slurry.
