Cuttability Investigation of Coated Carbides

Investigation of the Temperature-Related Wear Performance of Hard Nanostructured Coatings Deposited on a S600 High Speed Steel

“…The surface and microstructure characterization were performed by optical profilometry, field-emission gun scanning electron microscopy (FEGSEM), and energy dispersive spectroscopy (EDS).as extensively documented in the literature [12][13][14][15][16][17][18], the nanostructure of thin hard coatings has a remarkable influence on their tribological behavior.Common techniques available to modify the cutting tool substrate include chemical vapor deposition (CVD) and physical vapor deposition (PVD) [19]. Nowadays, PVD technology is preferred over CVD due to the lower operating temperature and the inner environmentally friendly nature of the process [20,21].Nitride-based hard coatings, obtained by a number of PVD processes, have found increasing applications owing to their combination of remarkable properties such as: (i) a high degree of hardness, (ii) excellent wear resistance, and (iii) corrosion resistance [22,23]. TiN was the first commercial PVD coating, firstly deposited back in the early 1980s [24].…”

Experimental investigation of surface roughness and chip morphology during machining of austenitic stainless steel 303 with pvd coated (TiAlN) insert

“…In order to improve the machinability and to obtain better surface quality with the machined components, surface modified tool inserts are used by the researchers like Chemical Vapor Deposition (CVD) coated tool inserts and Physical Vapor Deposition (PVD) coated tool inserts [19]. In the recent days, PVD technology has been commonly employed over CVD because of its low process operating temperature as well as environment-friendly nature [20]. Generally, AlTiN and TiCrN coatings show very good results in high performance metal cutting applications [21].…”
