“…Furthermore, the erosion resistance at ambient and high temperatures of oil and gas choke valves was evaluated, and thermal-treated austenitic stainless steel erosion behaviour was explored. Sliding wear was also the subject of research; themes regarding the sliding of polymeric pairs [292]], water-lubricated ceramics [293][294][295], high-chromium cast iron [296] and cobalt alloys [144,297,298] were studied. Besides that, the group has a synergetic partnership with prominent Brazilian tribology groups, such as LTM/UFU and LFS/USP, as well as international groups, such as the tribology group from the Institut Clément Ader, IMT Mines Albi-Carmaux.…”

This first regional issue published in STMP highlights the potential and importance of the research carried out in Latin America regarding surface engineering and tribology. In order to celebrate this important initiative, a complete historical account of Brazilian tribology is presented for the first time. It initiates with the first steps of Brazilian tribology in the 1980s, followed by the evolution and expansion of tribology research both in academic centres and industry. Focus is given to two outstanding achievements of Brazilian tribology: the fully flexible engines that run at any proportion of ethanol and gasoline and a fully innovative, completely oil-less family of hermetic compressors. The status-quo of the current research groups on tribology is described. Finally, the future trends envisaged by the Brazilian tribology community are presented.

“…Elevated temperatures also are present when ATZ materials are used as positioning pins. Many previous studies [4][5][6][7][8][9][10] have elaborated on the different aspects of ATZ composite processing, microstructures, and correlations with their final properties. Usually, attention has been focused on the zirconia/alumina ratio, phase composition, and sintering conditions (or methods).…”

An alumina-toughened zirconia (ATZ) material, fabricated using a procedure consisting of the common sintering of two different zirconia powders, was tested using the ball-on-disc method in a temperature range between room temperature and 400°C. Tetragonal zirconia balls were used as a counterpart. Two different types of microstructure were designed, one consisting of separated alumina inclusions in a zirconia matrix and another one which was a combination of two continuous phases, penetrating the whole volume of the composite. It was detected that at elevated temperatures both materials showed a distinct decrease in the wear rate. Composite with a low alumina content showed minimal wear rate at 300°C and composite with higher amount of alumina showed it at 400°C. There are some observations that this minimal wear rate result is connected with a pseudoplastic behaviour of a layer formed between co-operating elements of tribological pair. This layer is composed of the debris of both, sample and counterpart, and its behaviour during sliding is connected with the mean grain size of this debris which is correlated with the mean grain size of sintered material.

“…Different approaches can be pursued to optimize and tailor the tribological response of a system. In this regard, lubrication strategies based upon new lubricants such as water [28][29][30] or ionic liquids [31,32], tailored additives [33][34][35] or even solid lubrication [36][37][38][39] are subject of ongoing research activities. Moreover, the deposition of low shear-strength coatings, particularly by physical or chemical vapor deposition [40], has been proven to be an efficient way to control friction and wear.…”

Tailored surface textures to increase friction—A review

2022

View full text Add to dashboard Cite

Surface textures with micro-scale feature dimensions still hold great potential to enhance the frictional performance of tribological systems. Apart from the ability of surface texturing to reduce friction, surface textures can also be used to intentionally increase friction in various applications that rely on friction for their adequate functioning. Therefore, this review aims at presenting the state-of-the-art regarding textured surfaces for high-friction purposes. After a brief general introduction, the recent trends and future paths in laser surface texturing are summarized. Then, the potential of surface textures to increase friction in different applications including adhesion, movement transmission and control, biomimetic applications, and road-tire contacts is critically discussed. Special emphasis in this section is laid on the involved mechanisms responsible for friction increase. Finally, current short-comings and future research directions are pointed out thus emphasizing the great potential of (laser-based) surface texturing methods for innovations in modern surface engineering.
