Diamond-like carbon (DLC) is considered as a versatile coating material that finds a variety of mechanical and biomedical applications, including endoprosthesis and dental implants [1]. It provides mechanical robustness and cell-compatibility at the same time. Therefore, DLC has been extensively researched for achieving high hardness, low friction, high wear resistance to make it more sustainab...

Whilst resonant transmission is well understood and can be fully harnessed for crystalline superlattices, a complete picture has not yet emerged for disordered superlattices. It has proven difficult to tune resonant transmission in disordered diamond-like carbon (DLC) superlattices as conventional models are not equipped to incorporate significant structural disorder. In this work, we present c...

Diamond-like carbon (DLC) coatings are widely used in industries that require high durability and wear resistance, low friction. The unique characteristics of DLC allow for the possibility creating adsorption sites lubricant additives through doping process. In this study, combined use europium-doped diamond-like (Eu-DLC), gadolinium-doped (Gd-DLC), pure an ionic liquid (IL) additive, namely, t...

To clarify the friction durability, both during and after the high-temperature heating of nanometer-thick diamond-like carbon (DLC) films, deposited using filtered cathodic vacuum arc (FCVA) and plasma chemical vapor deposition (P-CVD) methods, the dependence of the friction coefficient on the load and sliding cycles of the DLC films, were evaluated. Cluster-I consisted of a low friction area i...

Ultra-thin diamond-like carbon (DLC) coatings are used in precision engineering applications, such as magnetic storage devices, to protect intricate structures from wear and corrosion. A DLC coating typically consists of hard amorphous carbon in combination with an interlayer such as silicon (Si), to improve adhesion to the substrate material. Deformation and delamination of these coatings, eve...

This article reports results of endothelial cell interaction with atom beam source N-doped a-C:H (diamond-like carbon, DLC) as it compares with that of Si-doped DLC thin films. The RF plasma source exhibits up to 40% N-dissociation and N-atomic fluxes of approximately 0.85 x 10(18) atoms/s, which ensures better atomic nitrogen incorporation. Two different types of nitrogen species (with and wit...

Abstract Friction modifiers (FMs) are surface-active additives added to base fluids reduce friction between rubbing surfaces. Their effectiveness depends on their interactions with surfaces and may be mitigated by the choice of fluid. In this work, performance an imidazolium ionic liquid (ImIL) additive in polyethylene-glycol (PEG) 1,4-butanediol for lubricating steel/steel diamond-like-carbon/...

We have developed capacitively-transduced nanomechanical resonators using sp(2)-rich diamond-like carbon (DLC) thin films as conducting membranes. The electrically conducting DLC films were grown by physical vapor deposition at a temperature of 500 °C. Characterizing the resonant response, we find a larger than expected frequency tuning that we attribute to the membrane being buckled upwards, a...
