Figure 15

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 free conditions–specimen immersion in potassium dichromate).
