“…Tungsten carbide with 6% cobalt (WC-Co) is a suitable substrate material, where cobalt is used as a binding agent. Cobalt provides additional toughness to the tool material [6,7]. It is possible to grow diamond crystal on the non-diamond substrate like silicon wafer or molybdenum which was reported by Matsumoto et al in 1982 [8].…”

Enormous developmental work has been made in synthesis of metastable diamond by hot filament chemical vapor deposition (HFCVD) method. In this paper, micro-crystalline diamond (MCD) was deposited on WC–6 wt.% Co cutting tool inserts by HFCVD technique. The MCD coated tool was characterized by the scanning electron microscope (SEM), X-ray diffraction (XRD) and micro Raman spectroscopy (μ-RS). A comparison was made among the MCD tool, uncoated tungsten carbide (WC) tool and polycrystalline diamond (PCD) tool during the dry turning of rolled aluminum. The various major tests were conducted such as surface roughness, cutting force and tool wear, which were taken into consideration to establish a proper comparison among the advanced cutting tools. Surface roughness was measured during machining by Talysurf. The tool wear was studied by SEM after machining. The cutting forces were measured by Kistler 3D-dynamometer during the machining process. The test results indicate that, the CVD coated MCD tool and PCD tool produced almost similar results. But, the price of PCD tools are five times costlier than MCD tools. So, MCD tool would be a better alternative for machining of aluminium.

“…Generally, cutting tools, sliding bearings, and drawing dies are manufactured from cemented carbides, which have a unique combination of properties: high intensity, abrasion resistance, vibration resistance, and impact resistance [1,2]. However, in recent years, the increasing application of new materials in some industries has led to higher requirements for cutting tools [3].…”

HFCVD method was used to prepare and characterize single and gradient multi-layered diamond coatings on tungsten carbide. The wear behaviour was evaluated in ambient air, against Si 3 N 4 ceramic balls. The results demonstrated that with the increase of carbon-source concentration from 1% to 5%, the diamond surface grains gradually refined and formed crystal clusters, and the roughness (Ra) of diamond surface decreased from 62.3 to 32.54 nm. Concerning the 100, 300, and 600 nm gradient of multilayer diamond coatings, the roughness Ra was 31.3, 35.6, and 40.5 nm, respectively. The diamond film obtained with 1% CH 4 concentration exhibited poor wear resistance. For higher CH 4 concentration, the abrasion resistance increased gradually. The average friction coefficient of multilayer diamond coatings decreased from 0.052 to 0.023 as the modulated layer thickness increased from 100 to 600 nm. The gradient multilayer structure significantly improved the tribological behaviour.

“…The effective way to improve the surface properties of materials is the high hardness and better wear resistance of nitride film [1]. TaN films have been widely used in the microelectronics industry for the film resistors and integrated circuit structural units due to their stable electrical properties [2].…”

A series of composite TaMgN films with various Mg content were deposited using reactive magnetron sputtering. The microstructural, mechanical, oxidation resistance and tribological properties of the films were measured. The results showed that when the Mg content is between 0 and 11.9 at.-%, the films are composed of fcc-(Ta,Mg)N and hcp-(Ta,Mg)N phases. While the further increase of Mg content induced the appearance of hcp-Mg phase and the films consisted of fcc-(Ta, Mg)N, hcp-(Ta, Mg)N and hcp-Mg, the hardness of the thin films was first increased and then decreased with the increase of Mg content due to the combined action of solution strengthening, internal stress and phase composition. The highest hardness value is 33 GPa, (Mg content is 11.9 at.-%). With a further increase of Mg content, the average friction coefficient further increased gradually, while the wear rate first decreased and then increased.
