The paper presents the results of some experimental researches concerning the electrical discharges deposition of the metallic powders an the workpieces cylindrical surfaces. The process could be included in the group of the manufacturing processes based on the physical effects of the electric current. The powder is introduced in the electrical discharge channel developed between the workpiece and the electrode. As consequence of the high temperature developed within the discharge channel, the powder and the superficial layer of the workpiece are melted and they constitute the new metallic layer, presenting more convenient properties from the point of view of the part behavior in service. Adequate mechanical and electric equipment was used to ensure the work conditions for the electrical discharge deposition The experimental researches were developed to study the influence exerted by certain work conditions on the man of the deposited material.
