Filed:

Oct 7, 1999

Appl. No.:

09/415850

Inventors:

Sandra J. Stash - Stanton CA
Mark E. Cooper - Vancouver WA

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

B05C 300

US Classification:

118429, 118612, 118602

Abstract:

A uniform coating of radar-absorbing material (RAM) is produced on small or intricate parts by suspending the part in a vessel, slowing filling the vessel with RAM slurry without turbulence from the bottom up, subsequently draining the slurry slowly without turbulence to leave a coating of RAM on the part, and repeating the process until a coating of sufficient thickness is obtained.
