MECHANISM OF FORMATION OF A CATHODE COATING IN A CARBON ARC
V. M. Anishchika, I. A. Pyzhova, I. P. Smyaglikovb, and V. D. Shimanovichb UDC 533.9:537.525.5 The structure and properties of carbon materials formed in an arc between graphite electrodes in the case of decreased pressure of a buffer gas are considered. A mechanism of formation of a cathode coating by positively charged carbon macroparticles is proposed. The particles melt upon collision with the cathode surface and then the stage of growth of a coating from a liquid phase occurs. aBelarusian State University, Minsk, Belarus; bInstitute of Molecular and Atomic Physics, National Academy of Sciences of Belarus, Minsk, Belarus; e-mail: 1phpp@imaph.bas-net.by.
