FACTORIAL EXPERIMENT AS A WAY TO DETERMINE THE MOST OPTIMAL ELECTRICAL PARAMETERS OF ELECTROEROSIVE DISPERSION PLANT FOR THE DISPERSION OF COPPER SCRAP IN DISTILLED

Today there is no available information on the production of powders, including copper powders, by electroerosive dispersion method. Thus any research of the said process seems important. Traditional experiments devoted to electroerosive dispersion process that involve successive modification of specific independent variables (such as the capacity of energy discharge capacitor, voltage, pulse repetition rate, etc.) with others being invariable (like medium, material, etc.) are rater complicated and demand much time, effort and resource. These are multi-factor experiments that are related with the optimization of material properties, identification of more optimal conditions of the electroerosive dispersion production process, development of the most efficient equipment design, etc. As a result the systems become too sophisticated to be studied within reasonable time period. Thus there is a need to find a way to boost research activities with ensuring final results that will approximate the most optimal solution. One of such ways is the statistical method of factorial experiment. The purpose of the present paper is to find the most optimal electrical parameters of electroerosive dispersion plant by making a full-scale factorial experiment and investigating the form and morphology of copper electroerosive powders obtained under the most optimal parameters of the production process. The most optimal electrical parameters of electroerosive dispersion plant have been determined by means of full-scale factorial experiment based on the efficiency of copper powder production process. It has been experimentally proved that the most optimal parameters for the production of copper powder by electroerosive dispersion in distilled water are as follows: capacity of the energy discharge capacitor of 45.5 мF, electrode voltage of 220 V, and pulse repetition frequency of 100 Hz.
