Wear and micromechanical performance of novel mono/bi-layered PVD-coated WC tools in high-speed turning of Ti-5Al-5V-5Mo-3Cr alloy

The Ti-5Al-5V-5Mo-3Cr alloy is utilized in the aerospace, biomedical, and military industries for its exceptional thermomechanical properties. However, its comparatively higher strength and toughness render it more difficult-to-cut than traditionally employed Ti alloys such as Ti-64. Despite its growing demand, a noticeable gap concerning the finish turning of Ti-5553 using coated carbide tools was identified. This paper aims to address this …
