Filed:

Sep 16, 2004

Appl. No.:

10/942222

Inventors:

Allen Simpson - Buchanan MI, US
Richard Smith - Marcellus MI, US
Marcia Wright - Niles MI, US
Phillip Johnson - Niles MI, US
David Cole - North Liberty IN, US

International Classification:

B05D 5/00
B05D 3/04
B05C 11/11

US Classification:

427256000, 427377000, 118504000

Abstract:

Mask () for use in coating a carbon-carbon composite brake disc () with anti-oxidant. The mask is composed of carbon-carbon composite material or nonreactive ceramic material. The mask is configured with edge ridges () that are aligned with the outer and inner annular diameters of the carbon-carbon composite brake disc, a gasflow channel () between the ridges, and a gas access port () that allows gas to enter the gasflow channel. The mask may also include a gas exit port () having a valve () operatively connected thereto, so that gas flow may be restricted when pressure within the mask and carbon-carbon composite brake disc falls below a specified minimum value. Also, a method of avoiding application of liquid antioxidant material to a friction surface of a carbon-carbon composite brake disc, by: covering the friction surface with a mask configured to deliver compressed gas to the friction surface, and directing compressed gas across the friction surface and through pores in the carbon-carbon composite brake disc and/or in the mask while the masked brake disc is in the presence of the antioxidant material in a liquid state.
