“…Because oxidation of materials is usually controlled by diffusion, 6–9 the relation of the reacted fraction ξ with temperature T and the heating rate η has been deduced in our recent work based on the Fick diffusion law 13 . The equation is as following: …”

The oxidation behavior of titanium nitride powder at different oxidizing atmospheres was investigated using thermogravimetric analysis, X‐ray diffraction, and scanning electron microscopy. Oxidation experiments have been carried out both in isothermal as well as nonisothermal modes. The nonisothermal oxidation result showed that the oxidation rate was affected by temperature, heating rate, and oxygen partial pressure. The isothermal oxidation result showed that the diffusion of oxygen through the oxide product layer to the oxide/titanium nitride interface was the rate‐controlling step and the oxidation product became obviously porous at elevated temperature. In view of the oxidation kinetics, Chou model, which quantitatively expresses the oxidation weight increment as a function of time, heating rate, temperature, and oxygen partial pressure, has been employed and gotten a good agreement.

“…The other kind of nanocomposites consists of those formed by crystals of a hard phase embedded in a soft phase. These soft phases usually have selflubricant properties and some examples from the literature are ZrN/Cu [11,12], TiN/CN x [13], WC/DLC/WS 2 [14] and many other transition-metal carbides dispersed in amorphous carbon (a-C) matrix namely as MeC/a-C (TiC/a-C [15][16][17][18][19], WC/a-C [20,21], TiBC/a-C [22,23]). …”

This paper tries to assess the factors governing the tribological behaviour of different nanocomposites films composed by metallic carbides (MeC) mixed with amorphous carbon (a-C). Different series of MeC/a-C coatings (with Me: Ti(B) and W) were prepared by magnetron sputtering technique varying the power applied to the graphite target in order to tailor the carbon content into the films. A deep investigation of the chemical and structural features at the nano-scale is carried out by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), electron energy-loss spectroscopy (EELS) and Raman spectroscopy techniques in order to establish correlations with the tribological properties measured by a pin-on-disk tribometer in ambient air. The analysis of the counterfaces by Raman confocal microscopy after the friction tests is used to follow the chemical phenomena occurring at the contact area responsible of the observed friction behaviour. The importance of determining the nanocrystalline/amorphous ratio is highlighted as a key-parameter to control the tribological properties. A comparative analysis of the mechanical and tribological performance of the three systems (TiC/a-C, WC/a-C, TiBC/a-C) is done and conclusions are obtained concerning the friction and wear mechanism involved.

“…The phase was identified as TiN. On the other hand, the Ti-B-C-N films deposited by Zhong et al [9,10] consisted of TiB 2 , TiC and TiN nano-crystallites, with particle sizes on the order of 2.5 nm embedded in a quasiamorphous matrix. This difference in the existing phases in the Ti-B-C-N film seemed to be due to the different deposition parameters and the different film compositions.…”

“…This difference in the existing phases in the Ti-B-C-N film seemed to be due to the different deposition parameters and the different film compositions. It is noted that Zhong et al [9,10] deposited the Ti-B-C-N film using RF magnetron sputtering under the condition of an RF power density of 11.2 W/cm 2 and a substrate bias of -50 V, while we deposited the Ti-B-C-N film using DC magnetron sputtering. The XPS spectra shown in Fig.…”

“…Ti-B-C-N films have been deposited by chemical vapor deposition (CVD) [7], magnetron sputtering [8][9][10], and electron beam-physical vapor deposition (EB-PVD) [11]. The metastable Ti-B-C-N films were harder than TiB 2 film [11], and displayed excellent tribological properties [8,9]. The oxidation resistance of the Ti-B-C-N films was recently studied to a certain extent [10].…”

Oxidation of Ti−B−C−N film deposited on steel

Ti-B-C-N films were deposited on tool steel substrates by a DC magnetron sputtering system, and their oxidation characteristics were investigated at the temperature range of 200°C to 800°C for up to 5 h in air. Ti-B-C-N films were oxidized to TiO2, which further reacted with FeO to become FeTiO3. The films did not display good oxidation resistance, owing to the evaporation of B, C and N into the air, film breakage, and poor film adherence owing to the mismatch of the thermal expansion coefficients between film and substrate.
