Polymers for Performance Tribological Coatings Product Range TriboShield® coatings are applied directly to the customer's component. 2015-6-2 · The tribological performance of a Bi+WS2 composite coating has been evaluated and compared with the performance of a STD Bi coating such as those currently used as overlay coatings in bearing applications in automotive market. The novel composite coatings exhibits The tribological performances of the coatings were investigated against GCr15 bearing steel on a ball-on-disc wear tester in open air. The results showed that with an increase in the Na 2 SiO 3 content, the working voltage of the MAO process decreased, the roughness and thickness of the coatings increased significantly, and the relative content 2021-2-26 · View all Tribological Materials Technologies. Bearing surfaces are typically either metal-on-metal (MOM), ceramic-on-ceramic (COC), or metal-on-polyethylene (MOP). MOM and MOP couplings have the drawback that metallic or polyethylene particles can sometimes separate from the couplings, which can cause significant problems, particularly in a Tribological dry coatings ensure integrated security of installation.” Open the catalog to page 2.

Anodic coatings are produced onto the surface of various components, made of aluminum alloys, in order to enhance their surface properties. The well-known classification of the anodic coatings is given in the MIL-A-8625F military standard, where hard anodic coatings belong to type III (Ref 1).

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.
