摘要
The purpose of the study is to determine the coated carbides tool life and the tool point surface topography. The study determined the cutting conditions in the process of turning duplex stainless steel (DSS), and detailed identification of wear mechanisms occurring on the rake face and major flank. The results of wear occurring on both tool points were compared with the width of the flank wear in relation to the period of the steady-state wear of the tool point. Occurrences of various mechanisms have been proven, such as abrasive wear and adhesion wear. Where machining without the use of a cooling lubricant occurred, longer tool life has been determined as well as a greater resistance to abrasive wear of the tools which were coated with Al2O3. Scanning electron microscopy (SEM) has been used for the wear analysis.
