coating process initiated by mechanical motion fig1 contains a diagram of a dry coating system 10 depicting various steps of the preferred dry coating process supplies of oxidizable component particles 12 and activating component particles 14 are added to a mixer 16 where the component particles are blended together portioned and then deposited through an applicator 18 onto a pre compactor 20 the deposited particles 22 form a pre compacted layer having a first thickness t 1 a compressor 24 further compacts the deposited particles 22 to a smaller second thickness t 2 to force collisions between the different particle components 12 and 14 for attaching the activating component particles 14 to surfaces of the oxidizable component particles 12 the second thickness t 2 is preferably at least one millimeter but is more preferably five to six millimeters which can be 100 to 1000 or more times the mean diameters of the component particles 12 a shearer 26 forces other collisions and rolling motions among the particles 22 to remove irregular accretions of the activating component 14 on the surfaces of the oxidizable component particles 12 a recirculator 28 collects the mixture of partially coated particles 22 and returns them to the mixer 16 where the particles are re blended and re portioned before being re deposited through the applicator 18 onto the pre compactor 20 each cycle through the dry coating system 10 provides for more evenly coating the surfaces.
