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/implicationseninfo:eu-repo/semantics/closedAccessPVD CoatingsSteelTool MaterialsTwo-body AbrasionWear ResistanceArticle65124312-s2.0-84921871926Q3
