Adhesion property and tool wear of hybrid deposited Ti0.67Al0.23Si0.09N coatings with WC grain size and Co content
Ti-Al-S-N coatings, characterized by a nanocomposite comprising nano-sized (Ti,Al,Si)N crystallites embedded in amorphous Si3N4 matrix, could be successfully synthesized on WC-Co substrates by a hybrid coating system (HCS) of arc ion plating (AIP) and sputtering method. Effects of WC grain size and Co contents on the adhesion strength of HCS-Ti-Al-Si-N/substrate interface were studied using a scratch test. The highest critical load, approximately 121N, was obtained at a WC grain size of 0.5mm and Co content of 10 wt.％. As the WC grain size and Co content of the substrate increased, the critical load was reduced. Cutting tests were carried out to evaluate the tool wear of Ti 0.67Al0.23Si0.09N coated end-mill tool in high-speed machining center. Ti0.67Al0.23Si0.09N coated tool with a WC grain size of 0.5mm and Co content of 10 wt.％ showed excellent wear-resistance in high-speed end-milling of the AISI D2 cold-worked die steel (62 HRC).
