Characterization and Parametric Optimization of Performance Parameters of DLC-Coated Tungsten Carbide (WC) Tool Using TOPSIS

In this work, we have deposited the diamond-like carbon (DLC) coating on tungsten carbide (WC) tool insert using thermal chemical vapor deposition (CVD) method. For growth of DLC coating, sugarcane bagasse was used as a precursor. Raman spectroscopy, field emission scanning electron microscope (FESEM), and X-ray diffraction (XRD) were to confirm presence inserts. The hardness tests also performed for inspecting microhardness induced by self-developed insert. To determine optimum process parameters turning operation an aluminum (6061) workpiece DLC-coated insert, applied technique order preference similarity ideal solution (TOPSIS) methods. considered optimization feed rate, cutting speed, depth cut. Whereas chosen response variables flank wear, temperature in zone, surface roughness. TOPSIS is utilized analyze effects selected input output parameters. This study paper revealed that it advantageous develop inserts machining applications. results 0.635 mm cut, rate 0.2 mm/rev, speed 480 m/min combination
