Journal ArticleDOI
Review on self-lubricant transition metal dichalcogenide nanocomposite coatings alloyed with carbon
TL;DR: In this paper, the authors review the results on the tribological behavior of nanocomposite coatings composed of nanoplatelets of transition metal dichalcogenides (TMD) immersed in a C-rich amorphous matrix.
Journal ArticleDOI

TL;DR: Platinum nanoparticles supported on graphite-rich boron carbide show a 50–100% increase in activity in acidic media and improved cycle stability compared to commercial carbon supported platinum nanoparticles, showing that purely electronic metal-support interactions can significantly improve oxygen reduction activity.
Journal ArticleDOI
Temperature dependence of tribological properties of MoS2 and MoSe2 coatings
TL;DR: In this paper, a comparison of tribological properties of transition metal dichalcogenides (MoS2) and molybdenum diselenide (MoSe2) coatings measured in air of different humidity and at elevated temperatures is presented.
Journal ArticleDOI
Comparison of tribological behaviour of TiN, TiCN and CrN at elevated temperatures
TL;DR: In this article, the wear data of PVD-coated instruments at temperatures exceeding room temperature were measured using a high-temperature tribometer (pin-on-disc, CSM Instruments).
Journal ArticleDOI
Sliding properties of MoS2 layers: load and interlayer orientation effects
TL;DR: In this article, the static potential energy surface and charge distribution analysis of two molybdenum disulfide sliding layers were modeled by means of an ab initio modeling.
