The wear of PVD coated elements in oscillation motion at high temperature

Properties of Diamond-like Tungsten-Doped Carbon Coatings Lubricated with Cutting Fluid

“…Figures [15][16][17][18][19][20][21][22] show SEM images of wear trace morphologies of the specimens and counter specimens after tribological tests. The surfaces were observed at magnifications of ×300 and ×10,000 (areas that were considered characteristic were magnified).…”

“…Their important functional characteristics are high hardness, wear resistance, and chemical inertness. These properties are inherent in diamond-like carbon (DLC) coatings consisting of bonds such as sp3, characteristic of diamond; sp2, characteristic of graphite; and sp1 with α and β carbine structures [15][16][17]. Due to their low friction coefficient, corrosion resistance and biocompatibility, DLC coatings are used in medicine for hip, knee, or shoulder implants, blood pumps, heart valves, or artificial heart components [18][19][20][21][22].…”

Reduction of dynamic loads in the drive system of mining scraper conveyors through the use of an innovative highly flexible metal coupling

“…Another way to reduce the forces acting in the meshing [26] is by avoiding transmission operation in the sub-harmonic or super-harmonic range of resonance, but this requires costly examinations at dedicated test rigs [41] or complex numerical simulations. Increasing the viscosity of the lubricating oil can also result in reduced inter-tooth forces on account of increased damping of the forces acting in gear meshing [25], but at the same time, this increases the hydraulic losses [4,13] in the gear transmission related to the oil mixing [45,46] and forcing through in inter-tooth spaces [55,62].…”
