Combined Metallurgical and Ceramic Coating in the Development of Tubular Ozone Generators

Abstract

Abstract This paper discusses the development of a metal-coated glass tube that produces ozone more economically than traditional methods. It describes the principle of ozone generation, provides information on ozonizer tubes, and presents the criteria for selecting thermal spray powders. It examines the properties of several multilayer coatings consisting of an oxide ceramic top layer, an Al/Si interlayer, and a borosilicate glass substrate. It was found that the porosity and surface roughness of the oxide layer have a significant impact on the dielectric strength of the composite and the efficiency of the ozone-producing tube.
