Modification of the composite multi-layer oxide ceramic coating on meteoroid shielding element by compression plasma flow

Porous silicon layers were formed on the silicon substrates treated with compression plasma flow. Pores density and lateral size on substrates treated with plasma is by 25% more than that on untreated substrates. The intensity of the PL of the PS layers, formed on the plasma treated substrates (PT PS), is twice more than that of the PS layers, formed on untreated substrates. Three month exposure of normal PS and PT PS layers to the air leads to the PL intensity increase by 3 and 5.7 times, respectively, as well as to the peak position shifting towards long wavelength region by 3.1 nm, in the case of PT PS layer. The PL intensity increase is attributable to the reduction of the dangling bond density as a result of passivation by oxygen.

Tremendous Impact

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.
