| Summary: | Title from the title-page. The new equipment - Computer Aided Measurement System (CAMS) as a tool for investigation of the physics-chemical characteristics of the ceramic layers by high current pulsed microplasma processes was developed. The CAMS has enhanced technical and metrological characteristics. The CAMS allows to record the volt-ampere characteristics of the pulsed microplasma processes at voltage up to 3000 V, the increased rate voltage up to 108 V/s, currents up to 100 A and control of the voltage and current with step-type behaviour of 25 mV and 1 mA accordingly. The developed method for recording of the volt-ampere characteristics uses the original trapezoid form of the pulsed polarization voltage. This method allows to separate an active and capacity parts of current during one pulse. The measured data can be used to predict a quality of ceramic layer: thickness, porosity, roughness, and dynamics of their changes. Some results of development and operation of the CAMS for electrical signals of the high current pulsed microplasma processes in the electrolytic solutions are submitted. Measurement of high-voltage and high-current signals of electrochemical cells is presented. The dependencies of the electrical signal form changes of the pulsed microplasma processes from the electrolyte composition, the layer formation time and working electrode material was carried out.
