SURVEY OF EFFECT OF SURFACE PROPERTIES ON ANODE EROSION,

Abstract

Anode erosion is a serious problem in high power electric arcs and appears to be due primarily to intense local heating. Three means are considered for amelioration: improved heat transfer from the anode spot, broadening of the anode spot (decreased power density), and reduction of total anode power dissipation. Low work function 'patches' may create preferred arc attachment points. Surface composition, structure, and preparation can have major influence, and means are discussed for tailoring anode surface properties. (Author)
