Tribological Properties of Ultrathin DLC Films with and without Metal Interlayers

Tribological behaviour of Mo–W doped carbon-based coating at ambient condition

“…Several approaches have been introduced to improve the adhesion strength of the DLC coating. As reported in the literature, Cr interlayer is introduced to decrease the compressive residual stress of the coating; therefore the adhesion strength is enhanced [7,8]. Another approach to overcome the aspects of low adhesion and high compressive stress is to incorporate W into the DLC coating.…”

Tribological properties of metal doped a-C film by RF magnetron sputtering method

“…6 shows the friction properties of various a-C:Me films. The coefficient of friction (COF) of a-C:Me films measured by AFM in the FFM mode [15] shows a similar value, and exhibit low values due to metal doping, and the minimum COF is about 0.52 for a-C:W film. The COF values of a-C:W films are relatively lower than that of other films fabricated in this work.…”

Development of DLC-Coated Solid SiAlON/TiN Ceramic End Mills for Nickel Alloy Machining: Problems and Prospects

“…The coating fills the micro-grooves on the surface, thereby providing a kind of "healing" of the surface (it should be noted that a similar effect is observed when applying coatings of various compositions). There is reason to expect that the coating will affect the characteristics of ceramic samples taking into account the described effect and the fact that the hardness of the formed DLC coating is not less than 25 GPa [73][74][75][76][77], which significantly exceeds the initial hardness of the tool ceramics, and the coating has a lower coefficient of friction and good strength of the adhesive bond with ceramic basis [78][79][80].…”
