INVESTIGATION OF PVD COATINGS FOR CUTTING TOOL APPLICATIONS
Keywords:
PVD, HSS, SEM, Hardness, Wear testAbstract
Enhancement of wear resistance has been a major interest for the cutting tool industry for few decades. Hence this work emphasizes the influence of the TiN and AlCrN coatings deposited on high speed steel form tool using Physical vapor deposition (PVD) technique. The microstructural studies of the above coatings were analyzed using Scanning electron microscope (SEM). Surface finish was measured by surface roughness testing machine. Hardness measurements were performed using Vickers hardness test. In addition to the above, the influence of the above coatings on the machining performance of the high speed steel was also evaluated and compared with that of the uncoated material.
