Abstract
A small object (12, FIG. 2) is coated by holding it in the pressure well (20) of an acoustic standing wave pattern, and then applying a mist of liquid coating material (42) at low velocity into the pressure well. The pressure gradient within the well forces the mist particles to be pushed against the object. A lower frequency acoustic wave (for oscillator 28, FIG. 4) also can be applied to the coated object, to vibrate it so as to evenly distribute the coated material. The same lower frequency vibrations can be applied to an object in the shape of a hollow sphere, to center the inner and outer surfaces of the sphere while it remains suspended.
