ELECTRO-SPARK COATING DEPOSITION MODEL TAKING INTO CONSIDERATION FORMATION OF LIGUID-BRIDGE BETWEEN ELECTRODES
The mathematical model of electrospark coating deposition is proposed. It describes a sequence of discharge events, as a result of which a bridge of molten electrode material is formed between the electrodes. When the electrodes diverge, the bridge is destroyed, and a layer of mixed alloy remains on the surfaces of the anode and cathode. Expressions for calculating the thickness and average density of the coating, changes in the masses of electrodes and the coefficient of mass transfer during electrospark alloying are found.
