Martens published his results “only” in the official journal of the Royal Prussian Technical Testing Institute, which has now become BAM (www.bam.de). The VDI journal being one of the most important journals for engineers, provided wide access to these data, and later colleagues rationalized the results into the three classical friction regimes online. It is discovered that the wear mechanism of composites is micro-cutting and fatigue stripping. A correlation exists between the wear resistance of composites and the strength of ceramic particles.

Fluid lubrication dynamics was established by Arnold Johannes Sommerfeld in 1900s. Horst Czichos 's systems approach, where appropriate material is selected by checking properties against tribological requirements under operating environment (H. Czichos,1978) Asset Management by Material Prognosis - a concept similar to terotechnology which has been introduced by the US Military ( DARPA ) for upkeep of equipment in good health and start-ready condition for 24 hours online. This faculty development opportunity was funded, in part, by CEMR’s Nason-Pritchard travel fund. “Active tribology is the ability to control the interaction between two surfaces in a mechanical system, thus improving performance or enabling a new function,” said Cairns. Cairns is developing active surfaces that can change roughness, and lubricants that can change viscosity in the presence of an electric field Lubricants Europe: The Directory of Lubricant and Lubricant Additive Suppliers in Europe http://old.gorvestnik.ru/library/lubricants-europe-the-directory-of-lubricant-and-lubricant-additive-suppliers-in-europe. Used on some services the O-ring could very quickly become clogged preventing the seal head from moving to accommodate wear of the faces. Incorrect setting length at installation. Just make sure that the fitting dimension is correct when installing the seal. Otherwise sometime in the future the seal will let go, usually after the pump is stopped, and the faces will look good but only partly worn , source: Tribophysics read for free http://britwayz.org/?library/tribophysics. Axial grooves are often used and, depending on their location relatively to the load line, they might substantially interfere with the hydrodynamic pressure generation and the thermal behaviour of the bearing. However, many of the existing tools for predicting bearing performance are not able to suitably predict bearing behaviour under varying load angle given the oversimplified way under which they treat lubricant feeding conditions ref.: Contact Mechanics in Tribology (Solid Mechanics and Its Applications) (Volume 61) http://old.gorvestnik.ru/library/contact-mechanics-in-tribology-solid-mechanics-and-its-applications-volume-61.

A "fret" ring is characterized by a polish mark on the shaft surface at the point where the seal elastomer seals against the shaft. If worn badly enough the fret ring can cause a new seal to fail on installation because the elastomer cannot seal effectively due to the damage on the surface , source: Advances in Medical Tribology Orthopaedic Implants and Implant Material old.gorvestnik.ru. Ans: Magnetic bearings can be designed to support thrust load, radial load, and combined load. Do air bearings require same conditions as magnetic bearings? Do they act as both thrust and radial bearings? Ans: Air and magnetic bearings are often recommended for oil-free high speed environment. Both kinds of bearings lack in damping and require active control system to handle instabilities Thin Films in Tribology (Data download online download online.

A 2013 study examined the interaction of hexadecanol with DLC surfaces using atomic force microscopy (AFM) and tribological testing. AFM indicated the amount of surface coverage, namely the size and the density of the adsorbed islands of alcohol molecules. Tribological tests were then performed to correlate wear and friction behaviour with the adsorption of molecules on the surface Introduction to Tribology in Industry Introduction to Tribology in Industry. Understanding the dynamic stability of bodies in frictional contact steadily sliding one over the other is of basic interest in various disciplines such as physics, solid mechanics, materials science and geophysics. Here we report on a two-dimensional linear stability analysis of a deformable solid of a finite height H, steadily sliding on top of a rigid solid within a generic rate-and-state friction type constitutive framework, fully accounting for elastodynamic effects ref.: Tribology Research Trends read online old.gorvestnik.ru.

Current efforts within Mechanical Engineering are in the research areas of: You want to export lubricants to foreign countries and need support in marketing or technic themes. After my mechanical engineering studies, with a diploma thesis about oil-dust lubrication in a steel mill, I'm active in the lubricant sector since 1971 ref.: Characterization of Tribological Materials (Materials Characterization Series) Characterization of Tribological. Tribology is an interdisciplinary field that includes mechanical engineering; materials science and engineering; chemistry and chemical engineering; and more. This wide variety of skills is necessary because many different physical phenomena occur at a sliding interface , source: Tribology 1972: Convention Proceedings http://old.gorvestnik.ru/library/tribology-1972-convention-proceedings. One of the reasons is the configuration of our hands, which enable us to hold items in a very convenient way. But further than that, we can actually grab items because of the friction coefficient that exists between the skin of our hands and the surface of the element we are picking up. For instance, grabbing a piece of ice might be a frustrating task, as its friction coefficient is very low and we cannot exert the necessary tangential forces in the contact surface to keep it fixed to our hand online. This results in increased costs due to more frequent tool replacement, loss of tolerance as tool dimensions shift, and greater forces are required to shape a piece. A layer of lubricant which eliminates surface contact virtually eliminates tool wear and decreases needed power by one third online. For each case, Hertzian pressure, Hertzian area, load, and entrainment velocity were kept constant while the ellipticity was varied by changing the curvature radii. In this context, the maximum central film thickness did not occur for the infinitely wide contact, but for a slender configuration close to the circular case , source: Thin Films in Tribology (Data Handling in Science and Technology) Thin Films in Tribology (Data Handling.
