Wear Evaluation on Turning Inserts Superficially Modified with Titanium Nitride by HIPIMS
Journal Title: Tribology in Industry - Year 2018, Vol 40, Issue 3
Abstract
The research aim evaluates the wear resistance of inserts for turning of tungsten carbide (WC), uncoated and coated with titanium nitride through physical vapor deposition (PVD) process by high-power impulse magnetron sputtering (HIPIMS) technique to different concentration of titanium (Ti) and nitrogen (N). The inserts were tested in turning of the grey cast iron of FC300 type at dry finishing conditions. The tips and cutting edges of inserts were analyzed before and later of tests by means of scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS). The obtained results of inserts wear were analyzed statistically using ANOVA tool, Tukey, and Taylor with the purpose of validating the HIPIMS technique as an alternative process of surface modification of the cutting tools for mechanized of grey cast iron, which material used in the manufacturing of liners and valves seats for gasoline, gas and diesel engines.
