Ferrous powder particles are coated with vaporized phosphorus in a fluid-bed reactor to obtain homogeneous coatings of phosphorus. The coated powders are useful feed for pressed structural parts, exhibiting improved green density, compressibility and sintered density thus improving magnetic and tensile properties.

Process for coating iron particles with phosphorus and forming compacted

A fluidized bed method and apparatus involving a grounded electrically conductive bed for controlling or eliminating electrostatic charges therein and high surface area charge dissipators.

Method and apparatus for controlling electrostatic charges in fluidized

A device for thermal shock testing and thermal cycling of workpieces is provided which comprises at least one fluidized bed chamber for thermally treating a workpiece. Agitation of the area about the workpiece is accomplished by movement of the workpiece, by baffles, or by providing a supplementary gas distributor. The agitation provided increases the flow rate of particles of the fluidized bed particulate media in a localized area about the workpiece, thus increasing the rate of heat transfer between the bed media and the workpiece, and increasing thermal shock capacity of the thermal shock tester.
