“…Due to a significant amount of material adhesion on the tool and the high chemical reactivity of titanium alloy, diamond could dissolve in the titanium matrix, convert into graphite or react with titanium, and crater wear was caused with the chips flowing away. Meanwhile, as the low thermal conductivity of titanium alloy and high thermal conductivity of diamond, the cutting heat mostly concentrates on the tool tip [6], which provides the condition for reaction of titanium [7] and raises the possibility of diamond graphitization [8]. Material adhesion also increases the rate of tool wear and the size of the crater as material adheres are removed over time.…”

“…With increasing the nickel content to 24 at.‐% (Ti 71 Ni 24 N 5 ) the chemical wear resistance significantly improves. This could be explained by the relatively high content of nickel, because research in Ti 60 Ni 40 coatings showed that these did not react with diamond 10. The non‐reactivity is ascribed to the covalent bonding in NiTi x which had been revealed by XPS.…”

“…A thermal contact test, based on the experiments of Ikawa and Tanaka9 and described by Kohlscheen et al,7,10 was performed to evaluate the chemical wear of diamond. The experiment was carried out in a vacuum chamber with a base pressure of 0.1 mPa.…”

“…For the sake of reducing the oxidization wear, Shimada et al (2000) performed the machining operations in the oxygen-free atmosphere. To be different, enriching the covalent bonds of the machining materials is an effective and promising solution to avoid the chemical reaction between diamond tool and the machining materials (Kohlscheen et al, 2002). In order to improve tool wear resistance, Yuan et al (1992) selected the desirable rake and flank faces according to the different frictional behaviours of diamond crystal planes.…”
