Changing the microstructure of the electrode surfaces during underwater electric discharges

Abstract

The article considers the advantages of electro-hydraulic method of drilling. The wear process of drilling electrodes during operation and process of the metal electrode erosion of the drill electro-hydraulic system have been studied. The dependence of the electrode wear rate on number of electro pulses has been established. Based on the experimental studies the authors determined the boundaries of the electrical parameters of the processing for the intensive destruction of solid rocks. Quantitative dependencies, characterizing the beginning of the process of destruction of rocks of different thickness depending on the number and energy discharges, have been investigated.
