AbstractIn this study, the super alloy Hastelloy C22 abrasion process was conducted with a copper electrode in electro erosion machine tools. The parameters used in the experimental study were three different pulse durations (10, 20 and 30 μs), waiting time (5, 10 and 15 μs) and discharge currents (5, 10 and 15 amps). As a result of the work done, the minimum mean surface roughness value was measured as 20 μs in the pulse duration, 10 μs in the wait time and 2.86 μm in the 5 amp current. The highest average surface roughness value was found to be 10 μs, 10 μs in the waiting period and 4.07 μm in the 15 amperes current.
