Nanoindentation and nanofriction on DLC films

Diamond-like carbon (DLC) coatings have been studied for many years as wear-resistant and low friction materials. Their tribological behaviour depends on the nature of the coating, which is determined by the deposition process. It is also strongly affected by environmental conditions. In this study, the nanomechanical properties and nanofriction behaviour of two a-C:H coatings deposited on a (PDF) Nanoindentation and nanoscratch behavior of The nanomechanical and wear performance of the coating was evaluated using nanoindentation, nanoscratch, dry sliding simulated tribotest and Vickers microhardness tests.

Diamond-Like Carbon (DLC) films have been shown to demonstrate various tribological behaviors:in ultra-high vacuum (UHV), with either friction coefficients as low as 0.01 or less and very mild wear, or very high friction coefficients (>0.4) and Analysis of nanoindentation and nanoscratch experiments Nanoindentation and nanoscratch experiments of diamond-like carbon coated (100) silicon surfaces under ambient conditions have been performed with a conical indenter on a Hysitron system, mounted on an atomic force microscope system. Single layers and Atomic Degradation and Wear of Thin Carbon Films Under The thermomechanical contact behavior and the resulting change in atomic structure of diamond-like carbon (DLC) film were investigated through molecular dynamics simulation. Under the high-speed sliding contact between a diamond asperity and an amorphous DLC film, the atomic stress, temperature rise, and atom coordination number were measured

Sep 14, 2012 · Nanoindentation, nanoscratch, and nanotensile tests were carried out to study the influence of different contents of FPPOSS on the key static and dynamic mechanical properties of different systems. The nanocomposite with 3 wt % FPPOSS was found to possess enhanced elastic properties and hardness. Self-Cross-linking Acrylate Copolymer/Organoclay (2014).

The nanomechanical and nanoscratch properties of MWNT Nanoindentation and nanoscratch tests were performed on the coatings to evaluate the mechanical and wear properties at small length scales. The mean values of elastic modulus and hardness were higher for the MWNT-reinforced coating, while the plasticity index of the coatings was unaffected.
