Entwicklung eines Breitstrahl-Plasmabrenners zur Behandlung planarer Oberflaechen (The Development of a Wide-Beam Plasma Burner for the Treatment of Planary Surfaces).

摘要

The study describes the development of an innovative wide-beam plasma burner which avoids the hitherto commonly found limitations in plasma burners and might open up new fields of application as well. The new plasma burner is compared to its predecessors in chapters two and three, the latter of which also includes a description of the usage parameters and potential of reactive plasma gases. Important characteristics of the arc discharge are discussed in chapter four. The stability of the arc discharge and the quality of the plasma lame are examined in chapter five by means of adapted electrical, magnetic, optical, acoustic, and calorimetric processes of measuring. The new burner shows marked improvement in safety, work conditions, and process gas composition.
