Özet
Purpose: This study compares the material removal performance of hardened steels DIN 115CrV3 coated with TiN and CrN using PVD method.Design/methodology/approach: New on-line monitoring wear system, thermal imager, and weight loss method were used to analyze to quantify and compare with uncoated tools.Findings: The results of abrasive wear experiments showed that weight loss increased with an increase in load applied for all tools. The microstructure and chemical analysis of each of the three tools showed some traces of abrasion and galling of Manganium from the workpiece. During abrasion test, thermal imager showed lower heating on the CrN coated tools. On-line wear analysis results show that at the low cutting speed (18 m/min), TiN-coated tools performed a higher wear resistance compared to rivals while at higher cutting speed CrN slightly show superior efficiency. The microstructure analysis of the tools confirmed fracture and galling on each of the tools.Research limitations/implications
