METHOD AND APPARATUS FOR COATING AN ARTICLE USING A SPRAY-COATING METHOD

摘要

The invention relates to a method and apparatus for coating an article using a spray-coating method. Coating can be produced by atomizing a fluid coating precursor material into droplets with an average diameter of 0.5 to 5 micrometres. The droplets are introduced onto the article to be coated at a velocity that exceeds the critical impaction velocity. The evaporation of the droplets can be controlled by controlling the concentration of the fluid precursor material solvent in the spray chamber.
