Sažetak

The objective of the investigation was to determine the surface integrity (SI) microhardness of austenitic stainless steel after turning with coated carbide tool point. Surface integrity is important in determining corrosion resistance, and also in fatigue crack initiation. The investigation included analysis of microhardness of SI for different cutting parameters in dry turning process of 1.4541 austenitic stainless steel. It has been shown that increase of cutting speed leads to the increase of SI hardening depth. The study has been performed within a production facility during the production of electric motor parts and deep-well pumps.
