Comparative wear behavior studies of coated inserts during milling of NiCrMoV steel

This paper contains the results of a tool wear study conducted to compare the performance of three coated carbide inserts during milling of NiCrMoV steel. Wear behavior of CVD TiCN/Al2O3/TiN and PVD TiAlN/Al2O3/ZrN multilayer coatings was compared on the milling inserts with different designs (various chip breaker groove angles). To understand the wear process, detailed XRD and SEM/EDS analysis combined with Raman spectroscopy of the worn …
