ABSTRACT:
Apparatus and method for coating interior surfaces of objects employs an electrostatic fluidized bed unit in which the fluidization chamber is relatively shallow, and is circumscribed by a marginal portion that conforms closely to the dimensions and configuration of the cavity of the object. The apparatus employs, as a feature of its recovery and recirculation system, a fluidized bed for agitating and facilitating feeding of the particulate material, thus making the system especially well suited for depositing coatings of abrasive materials, such as vitreous frit.
