Abstract: A component is treated in a fluidized bed by insertion of only a treatment part of the component into the treatment chamber of a fluidized bed apparatus. The non-treatment part of the component is located substantially outside the treatment chamber and out of contact with the fluidized bed. The boundary between the treatment part and the non-treatment part of the component is defined by a boundary containment surface at a fixed location with respect to the component. The boundary containment surface may be a seal which seals between the component to be treated and an aperture in a side wall of the treatment chamber.

Abstract: An apparatus for the treatment of a component using a fluidized bed of powder fluidized by a gas flow has a treatment chamber for receiving at least a treatment part of the component and for containing the fluidized bed. A fluidizing gas inlet provides fluidizing gas to the treatment chamber and a fluidizing gas outlet removes used fluidizing gas from the treatment chamber. A powder screen is located between the treatment chamber and the fluidizing gas outlet, the powder screen operable substantially to prevent loss of powder from the fluidizing bed entrained in the fluidizing gas removed from the treatment chamber. The treatment chamber can be small and moveable, and then applied to a part of a component to be treated. Heating of the fluidized bed may be provided by heating of the fluidizing gas in a fluidizing gas reservoir remote from the treatment chamber.
