Microstructural, Mechanical and Tribological Characterisation
0934: Microstructural, Mechanical and Tribological Chara
The results indicated that the enhanced tribological behaviour of the Micronite/UHMWPE sliding pair might be used as a material combination in artificial joints. Further studies are however required in order to support this. Examples of coatings which achieve this were also discussed, including nanocomposite and nanolayered coatings. Mention was also given to so-called ‘duplex’ coating systems, which combine surface treatments with coatings to gain maximum tribological benefits. 2021-04-23 · The study investigates thermal stability and high temperature tribological performance of a-C:H:Si diamond-like carbon (DLC) coating. A thin alumina layer was deposited on top of the a-C:H:Si coating to improve the tribological performance at high temperatures. The a-C:H:Si coating and alumina layer were prepared using plasma-activated chemical vapour deposition and atomic layer deposition Being deposited on various engineering materials, functional tribological coatings allow resolving contradictions between bulk and surface properties of engineering components.

Influence of the tool surface micro topography on the tribological
Similar damage mechanisms rarely occur for homogeneous materials. On the other hand, the typical mechanisms for gradual wear are the same for coatings … Tribological and Functional Coatings publications One of the keys to reducing friction and protecting against wear is to coat components with diamond-like carbon (DLC) or hydrocarbon layers. Further functions of components like reflection, sensors and barrier effect are adjusted via PVD coatings. A coating is a layer of a substance that is deposited over the surface of an object or a part, referred to as the substrate. Whatever the environmental temperature, coatings protect the surface of components and improve surface properties such as wear resistance, wear corrosion, and scratch resistance.

In particular, this requires lubricants with low vapor pressure that can withstand extreme temperature fluctuations. Open system tribology studies tribological systems that are exposed to and affected by the natural environment. The use of coatings to improve the tribological properties of components such as tools for metal cutting and forming, and machine elements e.g.
