On the wear mechanisms of uncoated and coated carbide tools in milling titanium alloys
Titanium alloys are known for being difficult to machine. Within the groups of Ti alloys, the machinability is reduced when going from the α-alloys, to α + β, and finally to near-β or β-alloys. Uncoated cemented carbide is traditionally used for machining these alloys and finding a suitable coating to improve the performance is a challenge due to the high strength of Ti alloys and the high chemica
