“…3 shows the Raman spectra of the diamond films grown on different substrates. It is found that the peak around 1332 cm−1 indicative of the sp3 bonding of diamond is visible for all the films [22]. From this figure, it can be seen that the Raman bands are present as 1338.2, 1336.4 cm−1 in diamond films deposited on conventional and gradient WC-10Co substrates, respectively.…”

Diamond coated tools of cemented carbide substrate with high Co content are extremely useful for machining difficult-to-cut materials. However, it is very difficult to deposit a well-adherent diamond coating on WC-Co with high Co content because of the strong catalytic effect of Co. In this work, a new functionally gradient WC-10wt. %Co hardmetal not containing η phase with a Co-depleted surface layer was fabricated. Diamond film was deposited on the gradient WC-10 wt. %Co by the hot filament chemical vapor deposition technique, and the quality and adhesion of diamond film were evaluated. The results indicate that the functionally gradient WC-10 wt. %Co hardmetal shows high adhesion strength to the diamond coating, and is a very promising substrate material for producing diamond coated tools.

“…In this case, understanding the wear characteristics of coatings at high temperatures is essential for advanced manufacturing engineering [6][7][8][9]. The diamond film is inert at normal temperature, while it is oxidized at high temperature, which leads to failing and destroys the protected cutting tools [10][11] due to its chemical reactions [12]. The working temperature of chemical vapor deposited diamond film is nearly equaled to that of the natural diamonds, which is oxidized at 800-900 °C.…”

Friction-wear behaviors of chemical vapor deposited diamond films at high temperaturesA diamond film was deposited on YT14 hard alloy cutting tool using a сhemical vapor deposition. The coefficients of friction and wear behaviors of the obtained diamond films at 500, 600, and 700 °C were investigated using a high temperature tribological tester. The results show that the C of diamond film is fully released at 700 °C, generating CO and CO 2 . The (220) plane of diamond film is oxidized fully at 500 °C, while the (110) plane of diamond film is oxidized at 700 °C. The average coefficients of friction of diamond film at 500, 600 and 700 °C are 0.55, 0.49, and 0.48, respectively, the wear mechanism is primarily oxidation wear, adhesive wear and abrasive wear, accompanied with fatigue wear.
