IMPROVED METHOD FOR PREPARING PRE-COATED ALUMINUM-ALLOY COMPONENTS AND COMPONENTS PREPARED THEREBY

摘要

An improved, pre-coated aluminum-alloy aircraft component prepared by providing an aluminum-alloy component precursor to a coating apparatus having a fluidized-bed or mist apparatus, suspending the components in the fluidizedbed apparatus vertically at a distance from the bottom of the apparatus and introducing a coating to the apparatus to coat the components while being suspended in the airstream flowing through the apparatus. The non-contact, fluidized-bed or mist coating method allows for the coating of increased batch sizes in shorter coating times with decreased variations in coating thickness and uniformity.
