Abstract : The patent describes a sealed chamber having means for evacuating the same and including means for suspending therein a workpiece to be coated and providing for the heating of said workpiece. A lower portion of said chamber contains the material for coating in fluidizable powder form. The coating powder is agitated and thereby fluidized the workpiece lowered and brought into direct contact with the fluidized bed while it is heated and the chamber is under vacuum.
