INNOVATIVE TECHNIQUE FOR IMPROVING THE DIELECTRIC AND ANTICORROSION CHARACTERISTICS OF COATINGS OBTAINED WITH THERMAL SPRAY, APS, HVOF AND ANALOGOUS TECHNOLOGIES, IN PARTICULAR INSULATING COATS SUCH AS AL2O3
An innovative technique for improving the dielectric and anticorrosion characteristics of coatings obtained with thermal spray, APS, HVOF and analogous technologies, in particular insulating coats such as Al2O3. The deposits obtained with APS, HVOF and analogous technologies generally have a varying inherent porosity but is particularly significant for insulating coatings such as Al2O3, which suffer badly, in the breakdown tests, from the corona effect, a characteristic of non-compact materials. Said porosity furthermore permits the occurrence of phenomena of corrosion of the substrate due both to oxidisation and to interaction with corrosive gases and liquids penetrating through the open pores. The use of a sealing agent consisting of a suspension of glass particles with appropriate granulometry and coefficient of expansion in specific liquids, for example screen-printed and re-melted, seals the open pores of the coats obtained with APS, HVOF or similar, thus preventing all phenomena of corrosion and drastically reducing the corona effect.
