For the abrasion phenomenon of the turbine flowing-passage components was very serious, the electrical discharge machining (EDM) surface strengthening process of stainless steel 1Cr13 by different electrodes were carried out in this paper, the formation laws and influencing factors of the EDM surface strengthening layer are researched deeply. The correspondence relation between strengthening layer thickness and enhancing time, electrode materials, and electrical parameters are obtained by the detailed theoretical analysis and experimental investigation. The results show that, in the premise of the strengthening layer thickness, workpiece quality and machining efficiency, the strengthening process can be improved by reasonable selecting and controlling the process parameters such as discharge voltage, capacitance, pulse frequency, peak current, pulse width and enhancing time.
