Abstract

This article discusses the development of a novel efficient ozonizer tube which cuts down the production costs and thus causes ozone to be an economically competitive alternative in comparison to traditionally used chlorine compounds. It describes the principle of ozone generation, provides information on improved ozonizer tubes, and presents the criteria for selecting thermal spray powders. The article investigates several types of thermal sprayed multilayer coatings, consisting of an Al/Si intermetallic interlayer and an oxide ceramic top coating on a borosilicate glass. It was found that the structural constitution namely, porosity and electrode surface roughness of the oxide layer, has a tremendous impact on the dielectric strength of the composite.
