Mechanical and tribological properties of multicomponent Ti–B–C–N thin films with varied C contents

An investigation on the microstructure, tribological and corrosion performance of AISI 321 stainless steel carbonitrided by RF plasma process

“…The superior tribological properties of the treated layer are ascribed mainly to harder nitride phases especially γ N [62,63]. Furthermore, the existence of carbide phases and amorphous compounds in the near surface region at higher carbon content reduces the wear rate of the examined samples due to their lower friction coefficient [61]. Moreover, the oxide layer has a double maker role in the wear process of untreated and treated substrates.…”

“…Chromium nitride with different contents is considered for the decreasing of the friction coefficient of the nitrided sample [60]. Last and not least, the plate-like wear debris formed from the adhesive transfer could be also considered [61].…”

Characterization of Ti-B-C-N films deposited by dc magnetron sputtering of bicomponent Ti/B4C target

“…For these reasons, they have been used for hard wear-resistant coatings in machining industry, diffusion barriers in microelectronics, and electrodes in semiconductor devices. The demand for advanced coatings with further improved mechanical, corrosion, and tribological properties has recently led to more complex coatings, in particular of Ti-B-C-N system [7][8][9][10][11][12].…”

“…Nanocomposite coatings of the Ti-B-C-N system can be obtained by a variety of methods, such as dc or rf reactive (in the mixture of argon and nitrogen gases) magnetron sputtering of TiB 2 /TiC composite target [7], Ti/B 4 C compound target [8], separate C, Ti, and TiB 2 targets [9], separate C, Ti, and B 4 C targets [10], single Ti and TiB 2 targets (in this case sputtering is carried out in the mixture of argon, nitrogen, and acetylene gases) [11]. The methods of cathodic arc plasma evaporation [9] and CVD (in which various precursors are used) [13][14][15] have also been applied for deposition of coatings of the Ti-B-C-N system.…”
