Improving coated carbide tool life through wide peening cleaning (WPC) during the wet milling of H13 tool steel

The (AlCrN–TiAlN) bi-layer PVD (physical vapor deposition) coating was post-treated by a wide peening cleaning (WPC) process at various pressures and times. The micro-mechanical and adhesion properties of the studied coatings were evaluated in terms of their effects on machining performance during the wet milling of H13 tool steel. A comprehensive characterization of the cutting-edge geometry was performed by infinite focus microscope and EDX …
