Compared with the antibacterial materials prepared by other methods, the modified titanium dioxide used in this study can absorb visible light and the particle size is less than 100 nm (Table 1). As far as we know, the high-energy ball milling process is rarely used for photocatalytic antibacterial of modified TiO 2.
Milling titanium is like milling other hard-to-machine metals in that a small increase in cutting speed can lead to a big increase in edge wear. Milling titanium is different from other metals because of the risk of heat build-up. Thanks to the metal's low thermal conductivity, overly aggressive milling may even pose a risk of combustion. ...
Titanium can pick up interstitial elements very easly. Milling in a protective atmosphere is mandatory (e.g. Argon). high energy milling can promote cold welding as well because Ti is ductile, if ...
