Patent ID: 8721761

Claim:
A surface covering composition adapted for disposition in overlying bonded relation to a metal substrate, the surface covering composition comprising a plurality of metal carbide particles disposed within a metal matrix at a packing factor of not less than about 0.6 as measured by area occupancy ratio of the carbide particles within a defined measurement zone within the surface covering composition, the defined measurement zone extending from the metal substrate to a position about 3 mm above the metal substrate, at least 40 percent by weight of said metal carbide particles being characterized by an effective diameter in the range of +14-32 mesh prior to introduction to the metal matrix, at least 10 percent by weight of said metal carbide particles being characterized by an effective diameter in the range of +32-60 mesh prior to introduction to the metal matrix, and at least 3 percent by weight of said metal carbide particles being characterized by an effective diameter in the range of +80-120 mesh prior to introduction to the metal matrix.
