摘要：
The paper examines how the porosity of electrode materials used to restore parts influences the electrospark deposition process. A higher porosity decreases the heat conductivity of the electrode material. A smaller amount of heat spreads along the electrode and, hence, a greater amount of heat remains for melting. Erosion and deposition of the material increase accordingly.
