“…The surface was polished to provide an arithmetic roughness Ra of less than 0.1 m. Fig. 1 shows a scanning electron micrograph of the microstructure of this SiC etched by boiling Murakami's reagent (45 g of K 3 Fe(CN) 6 , 40 g of NaOH and 200 mL of H 2 O). The average size of the silicon carbide grains is about 5 m. Black regions are identified as graphite, boron carbide B 4 C and porosities.…”

“…Silicon carbide offers good mechanical properties (high hardness, high Young modulus), good corrosion resistance and good thermal conductivity, that make it suitable for tribological applications in different atmosphere (in air, argon or vacuum) 1,2 and in dry or lubricated sliding. 3,4 Overall, it shows a coefficient of friction in the range of 0.2-0.7 and a low wear rate, particularly when lubricated. [5][6][7] Combined with a counter-face ring made of a softer carbon-graphite, the dry sliding of SiC can be sustained even under severe conditions of pressure and speed.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. AbstractTribological properties of a silicon carbide in homogeneous contact configuration are often related in lubricated or even dry conditions but only for ball or pin-on-disk configurations. The present study develops an experiment using a ring-on-ring device under dry friction in order to better match the industrial needs for dry mechanical seals applications. Tribological tests were run at a temperature of 120• C, a sliding speed of 2 m/s and a contact pressure of 0.15 MPa on SiC/SiC and SiC/C pairs, with different impregnated carbon materials. The measurements were sensitive to the formation and the circulation of the third body at the contact interface. This third body was mainly composed by carbon, oxygen and the carbon impregnants. An amorphization process of the tribofilm was revealed by using Raman spectroscopy. Based on chemical analysis and mechanical considerations, the wear mechanisms were found to be driven by cracking process and oxidation.

“…Als typische Reibwerte wurden fu Èr die Misch-/Grenzreibung zwischen 0,05 und 0,15 [32] sowie fu Èr den ungeschmierten Zustand Werte von 0,5 verwendet. Fu Èr die Normalkra Èfte wurde 4000 N und 8000 N und fu Èr die Gleitgeschwindigkeiten 10 mm s À1 und 30 mm s À1 gewa Èhlt, um so den maximal mo Èglichen Beanspruchungsbereich (s. Tabelle 3) eines Gelenkes zu erfassen.…”

Bei Hüftgelenkersatz reduziert die Verwendung von Kugelköpfen und Pfannen aus Aluminiumoxidkeramik die Abriebrate. Es wird der Einsatz Y‐TZP Zirkondioxidkeramik vorgeschlagen. Die Vorgänge an den Artikulationsflächen Kopf/Pfanne sind nicht vollständig verstanden, besonders die durch Reibwärme verursachte Temperaturerhöhung. Bei der phasenstabilen Aluminiumoxidkeramik werden keine ungünstigen Effekte beobachtet, bei Y‐TZP dagegen kann durch reibbedingte Temperaturerhöhung und das Herauslösen des Yttriumoxides die Phasenumwandlung des Y‐TZP ausgelöst werden und das Herauslösen des Yttriumoxides. Mit Hilfe des Modells nach Blok, Jaeger und Kuhlmann – Wilsdorf sind unter in vivo Randbedingungen die Blitztemperaturen in den Mikrokontakten der verschiedenen keramischen Artikulationspartner bestimmt worden. Die Oberflächentemperaturen sind für die Gleitpaarung Y‐TZP/Y‐TZP höher als für Al2O3/Al2O3.

“…Recently, researches on tribology of ceramic/metal and ceramic/ceramic pairs in sliding contact becomes important for a lot of engineering applications, including roller bearings, journal bearings, seal rings, valves, artificial joints and parts for internal combustion engines [3]. For example, Aronov and Mesyef [4] investigated wear mechanisms in sliding contact of partially stabilized zirconia rubbed against itself and against different kinds of steels at high temperatures and exhaust gas environment in combustion systems.…”

Active Control of Boundary Lubrication of Ceramic Tribo-Pairs in Sodium Dodecyl Sulfate Aqueous Solutions

The objective of the study is to actively control friction between engineering ceramics in underwater applications. By designing a proper electrode system and applying an external electric field, the active control of friction between Al 2 O 3 plate and ZrO 2 ball in sodium dodecyl sulfate (SDS) aqueous solutions has been realized, which is different from the previous studies of potential controlled boundary lubrication where at least one part of tribo-pairs is a conductor. Reversible change of friction coefficient has been observed in the range from 0.12 to 0.35. An indirect electric field-assisted adsorption model has been proposed to explain the observed phenomena. The addition of inorganic salts containing counterions to the SDS solution or increasing the concentration of SDS can shorten the response time of friction to the variation of the applied electric field by facilitating the formation of SDS micelles. This opens a new way to realize the active control of friction for insulative tribo-pairs without corrosion.
