Electrostatic fluidized bed spraying is a coating process that is often used for coating plastic. A novel flame spray technology with a controlled atmosphere was developed by Air Liquide in order to realize coatings with thermoplastics as well as composite coatings such as plastic/ceramic or plastic/metal. This technology expands the scope of the applications of plastic coatings especially for all types of shapes and materials as well as for on-site coating. Two types of powder, namely Rilsan and Gotalene were used in this study. The tests were carried out by HTI, which is Air Liquide's partner in the development of such applications. After introducing the principle of this process, this paper presents and discusses the coating process and the properties of such coatings. Then the advantages and limitations of the process are highlighted. Paper includes a German-language abstract.
