“…With the action of atomic hydrogen, a serious of adsorption and desorption reactions of these groups will occur, leading to the nucleation and growth of a diamond film on the substrate surface. [4][5][6][7][8] In recent years, the development and application of diamond-coated tools was explored by several researchers. The cutting performance of diamond-coated WC-Co tools was demonstrated to be greatly superior to the uncoated tools.…”

Monolayer and multilayer diamond films are deposited on WC‐Co cemented carbide by hot‐filament chemical vapor deposition. The growth characteristics of diamond coatings are analyzed. Cutting performance characteristics such as tool life and the stability of machining process in the machining of presintered ZrO2 are compared based on the variation of cutting speed and resultant cutting force, and workpiece surface roughness. For the monolayer diamond coatings, as the concentration of CH4 increases from 1% to 5%, the diamond crystal is transformed from micron columnar crystal to nanocluster crystal. The multilayer diamond coatings combine the advantages of micron‐ and nanocrystalline structures. The multilayer diamond‐coated tool exhibits longer service life and better machining quality. Because of the appearance of the brittle–plastic conversion mechanism, the surface integrity of ZrO2 processed by multilayer diamond‐coated tool is relatively high. As for the uncoated tool, the workpiece is mainly machined by brittle spalling. The interfacial stratified fracture system between the interlayers is proposed to be the toughening mechanism of the multilayer structure.

“…The chemical vapor deposition (CVD) technique allows the engineering of various single-and poly-crystalline diamond materials [1] with a control over their crystalline quality [2][3][4], chemical purity [5][6][7] , as well as the design of new composite [8][9][10][11] and multi-layered structures [12][13][14]. Such a variety of CVDgrown diamond materials is in high demand for gem industry [15], optics/photonics [16][17][18], electronics [19,20], tribology [21], biomedicine [22], et c. For all these applications, the control over structure and characteristics of the synthesized material is extremely important.…”

“…In addition to modifying the composition and microstructure of hard alloys [2,3], surface modification is an important way to improve the performance and service life of cemented carbide components [4][5][6]. Vacuum vapor deposition is the dominant technology in this field, so far; more than 85% of cemented carbide cutting tools are coated with hard films or carbon-based films [7][8][9]. In addition, ion implantation (IIP), heat-treatment, deep cryogenic treatment (DCT), and high-energy electron irradiation (HEEIR) are state-of-the-art techniques for enhancing the complex properties of cemented carbide alloys [10][11][12].…”

Effect of Low-Pressure Plasma Nitriding with Hollow Cathode Discharge on the Surface Microstructure of WC-Co Cermet

et al. 2021

WC-Co cermet was plasma-nitrided with the assistance of a hollow cathode ion source at 400 °C under a vacuum of 3–8 Pa. Hot film chemical vapor deposition (HFCVD) of a diamond coating was carried out on the nitrided specimen, without chemical etching. Scanning electronic microscopy, electron probing microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy were used to characterize the surface microstructure of the nitride specimens and the coatings. A thin surface conversion layer with a specific structure was formed, in which the primary Co binder was transformed into Co-rich particles. The Co-rich particles consisted of a γ-Co core and a Co4N outer layer. This specific surface conversion layer significantly suppresses the out-diffusion and catalytic graphitization of Co during HFCVD. The existent phase, morphology, and density distribution of Co compounds can be tuned by varying the nitriding parameters, such as gas media, ionization ratio, bombardment energy flux, and nitriding duration.
