FIELD: metallurgy.
SUBSTANCE: electro-chemical cell for production of porous anode metal oxides and semi-conductors consists of flat heat conducting holder of sample made out of chemically inert material, of working electrode in form of strip metal electrode arranged along perimetre of working surface of sample on its periphery isolated from electrolyte, of sample, of bath with electrolyte contacting sample, of auxiliary electrode located in volume of electrolyte, and of device for control of temperature in electro-chemical cell contacting back surface of sample holder. A generator of supersonic oscillations is attached to back surface of the sample holder.
EFFECT: raised repeatability of process of forming porous anode oxides of metal and semi conducting samples.
