Ultrasonic characterization of mechanical properties of Cr- and W-doped diamond-like carbon hard coatings
Two ultrasonic nondestructive evaluation methods have been applied to systematically characterize the mechanical properties of nanostructured physical vapor deposited diamond-like carbon (DLC) ultra-hard coatings. A photoacoustic guided-wave technique is used to generate broadband surface acoustic waves (SAW) on the coating surfaces, and dispersion relations of the SAW for DLC coatings are meas...
متن کاملOrigin of magnetism and quasiparticles properties in Cr-doped TiO2.
Combining the local spin density approximation (LSDA)+U and an analysis of superexchange interactions beyond density functional theory, we describe the magnetic ground state of Cr-doped TiO2, an intensively studied and debated dilute magnetic oxide. In parallel, we correct our LSDA+U (+ superexchange) ground state through GW corrections (GW@LSDA+U) that reproduce the position of the impurity st...
متن کاملPorous boron-doped diamond/carbon nanotube electrodes.
Nanostructuring boron-doped diamond (BDD) films increases their sensitivity and performance when used as electrodes in electrochemical environments. We have developed a method to produce such nanostructured, porous electrodes by depositing BDD thin film onto a densely packed "forest" of vertically aligned multiwalled carbon nanotubes (CNTs). The CNTs had previously been exposed to a suspension ...
متن کاملNitrogen-Induced Degradation of Corrosion Resistance of Platinum/Ruthenium/Nitrogen-Doped Diamond-like Carbon Thin Films
An influence of nitrogen incorporation on the chemical composition, bonding structure, surface morphology and activity, adhesion strength, and corrosion resistance of platinum/ruthenium/nitrogen-doped diamond-like carbon PtRuN-DLC thin films deposited on conductive p-Si 100 substrates using dc magnetron sputtering deposition was investigated using X-ray photoelectron spectroscopy, micro-Raman s...
متن کامل24 Tribology of Diamond , Diamond - Like Carbon , and Related Films
Diamond, diamond-like carbon (DLC), and other related materials (i.e., carbon nitride and cubic boron nitride [CBN]) are some of the hardest materials known and offer several other outstanding properties, such as high mechanical strength, chemical inertness, and very attractive friction and wear properties, that make them good prospects for a wide range of tribological applications, including r...
