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.
