コーティングされた炭素・ブレーキディスク材料
Document Type and Number:
Japanese Patent JP2005534598
Kind Code:
A
Abstract:
Antioxidant coating compositions containing 10-75 wt % H2O, 20-65 wt % H3PO4, 0.1-20 wt % alkali metal mono-, di-, or tri-basic phosphate, 0-2 wt % hydrated boron oxide, 0-18 wt % KH2PO4, 3-10 wt % of a transition metal oxide, and 0-20 wt % hydrated manganese phosphate, 0-25 wt % Al(H2PO4)3, and 0-10 wt % Zn3(PO4)2, provided that at least one of Al(H2PO4)3, Zn3(PO4)2, 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 matrix 15 of brake disc 11 is covered on its outer and inner edges with antioxidant layers 19 and portions of the working surface of brake disc 11 may also be covered with antioxidant layers 13 , potentially decreasing the fitness of the brake disc for service. In accordance with this invention, brake disc 12 is manufactured from brake disc 11 by the removal from its working surface of antioxidant layers 13.
