Abstract
Antioxidant coating compositions containing 10-75 wt % HO, 20-65 wt % HPO, 0.1-20 wt % alkali metal mono-, di-, or tri-basic phosphate, 0-2 wt % hydrated boron oxide, 0-18 wt % KHPO, 3-10 wt % of a transition metal oxide, and 0-20 wt % hydrated manganese phosphate, 0-25 wt % Al(HPO), and 0-10 wt % Zn(PO), provided that at least one of Al(HPO), Zn(PO), and hydrated manganese phosphate is present. Also, brake discs made from carbon composite articles having their surface treated with certain antioxidant coatings. During a manufacturing process, carbon matrixof brake discis covered on its outer and inner edges with antioxidant layersand portions of the working surface of brake discmay also be covered with antioxidant layers, potentially decreasing the fitness of the brake disc for service. In accordance with this invention, brake discis manufactured from brake discby the removal from its working surface of antioxidant layers
