Abstract: The method has the fluidisation occurring in a twin chambered device (2), the first chamber (3 )receiving the compressed air that then passes through a "frit" to the second chamber(4). The powder in the second chamber leaves the device from the nozzle (11) and is charged up. The powder is filled through the hole (9) which can be closed off. Apart from the nozzle and the air inlet and outlet valves (17,19), the fluidisation takes place in a closed chamber, the valves being used to maintain the correct pressure proportions. Additional mechanical energy is passed to the fluidised bed of the second chamber in the form of vibration.

Abstract: The coating involves at least two applicators (1,2), a corona spray gun and a tribo spray gun. One applicator (1) sprays the workpiece with positive charged particles of the covering material and the other applicator sprays it with negative charged particles. The two applicators work at the same time. The application of the particles of different charge at the same time means that the surface charge is less than when there is only one application of particles of one charge so the covering is thicker. Alternatively two applicators spray two different materials each having a different electric charge. The covering is sprayed alternating between the two applicators and thin layers are sprayed.
