Considerations on the Specific Phenomena in Metal Heating when Using Electrolytic Plasma

Abstract:

Discovered in 1930, metal processing by electrolysis processes in aqueous solutions, are being intensely studied starting with 1960, so that now they have a wide diversity and industrial applicability. The present paper illustrates some theoretical considerations regarding specific electrode processes of the aqueous solutions electrolysis and the I=f (U) characteristics of the Me/VGS/E electrochemical system thus establishing the forming conditions of electrolytic plasma (PE). The continuous and stable character of the deposited layer (VGS) and of the shell formed by the electrolytic plasma will contribute to the rapid heating of the metal electrode, under the influence of the three heat flows q_a, q_l and q_s. Plasma electrolytic saturation phenomena (PES) and the formation of oxides on the metal surface (PEO), represent the two main directions of plasma electrolytic deposition (PED).
