Exploitation and Wear Properties of Nanostructured WC-Co Tool Modified with Plasma-Assisted Chemical Vapor Deposition TiBN Coating

In recent years, coated cemented carbides have often been the first choice for a wide variety of tool inserts and applications. Its success as cutting material arises from unique combination wear resistance toughness, its ability to be formed into complex shapes. The structure obtained by sintering nanoparticle powders provides significant improvement in product properties, such higher speeds, lower tolerances, longer service life. this study, multi-layered gradient coating, deposited on nanostructured plasma-assisted chemical vapor deposition (PACVD) was investigated with emphasis exploitation properties. TiBN coating carbide samples addition 5 wt% Co, 10 Co 15 Co. were consolidated one cycle hot isostatic pressing (HIP) technique. Complex architecture built TiN TiB2 multilayer sequence block each type substrate. Wear determined erosion testing dry sliding (ball-on-flat test). friction coefficients ~0.22 ball-on-flat test show decrease when compared uncoated values ~0.32. absence rupture confirmed track depth measurements showing trace ~1.2 ?m. Exploitation properties i.e., life determination using single-point turning commercial insert K10 tested under same conditions. All conducted tests excellent newly developed chosen conditions, including speed, vc = 200 m/min, cut, ap 1 mm, feed, fn 0.2 mm. Coated WC-Co having withstood min machining flank size less than 0.3 suggest 0.56 mm insert.
