Abstract: A METHOD OF PROTECTING THE SHARP CORNERS OR EDGES OF A CARBON STEEL BASE FROM CORROSION. A CORROSION RESISTANT METAL IS SPRAYED ONTO THE EDGES OF THE CARBON STEEL TO BE PROTECTED TO PROVIDE A CORROSION RESISTANT COATING ON THE EDGES. SUBSEQUENTLY A GLASS SLIP IS APPLIED TO THE ARTICLE AND OVER THE POROUS METAL COATING. THE ARTICLE IS THEN FIRED AT AN ELEVATED TEMPERATURE, ABOVE THE MELTING POINT OF THE

GLASS, TO MELT THE GLASS AND THE MOLTEN GLASS FLOWS TO COMPLETELY FILL THE VOIDS IN THE POROUS METAL COATING.
