Figure 16: Comparative results. Investigation of abrasive wear resistance measured with Skoda-Savin method: (I) samples of steel 45 machined by grinding, (II) EDM—U = 180 V, I = 32 A, Ti = 800 μs and EDA: U = 200 V, I = 24 A, Ti = 400 μs; (III, IV) EDM, EDA and with roto peen:  rev/min for the time of:  s (III);  s (IV). (Lubrication conditions—kerosene and machine oil solution −1 : 3).
