Abstract
Due to the growing application fields, the development of plasma generators has become increasingly important in recent years. Nowadays, DC-plasmas used for a plethora of coatings on metallic surfaces, metallization of plastic materials, surface cleaning and activation, plasma welding and spacecraft propulsion systems. The use of plasma generators for surface coating has grown enormously in the field of thermal insulation and wear-resistant coatings, especially with regard to deposition of refractory oxide ceramic layers using powders such as aluminum oxide, alumina / titania, zirconia and chromium oxide. In addition, for the plasma-assisted surface treatment, generators for both wide extended planar surfaces, as well as structures that are more complex have designed and industrially established. Nonetheless, new plasma sources still developed to provide more-efficient, tailor-made solutions due to their specific characteristics. Within this paper, a brief overview of the new innovative development of DC-plasma generator “Penta” shown. Thereby the special setup, first diagnostic results, including coatings, presented and discussed. The paper concludes with an outlook for future diagnostic measurements and possible future applications for this DC-plasma torch.
