“…As the thermal resistance and thermal conductivity of UHMWPE was low, with the increase of rotation speed and the accumulation of sliding distance, a large amount of frictional heat would be generated and accumulated on the contact interface, and this would lead to softening of the surface layer at the material interface if the temperature on the contact interface exceeded the softening temperature of UHMWPE material. The lower shear stress and better surface mobility in the surface layer of the material because of the accumulation of frictional heat, which made it easier for the material on the contact surface to stretch in the sliding direction, 52 and eventually the adhesive wear would occur on the worn surface, as shown in Figure 13 (a 3 ). Further, the flowing softened layer could also effectively fill the gap between the protrusions on the surface of the material, increasing the actual contact area of the friction pair, effectively improving the lubrication performance, decreasing the coefficient of friction, and reducing wear on the metal surface.…”

To better understand the damage failure mechanism of ultra‐high molecular weight polyethylene (UHMWPE) in engineering application environments, a study was conducted to explore the effect of rotation speed on its abrasive wear performance in lubricant media containing abrasive particles, especially in comparison to the water. The wear mechanism was analyzed by friction coefficient and wear behavior. The results show that UHMWPE has excellent tribological properties in the water and is seriously worn in the abrasive environment. Under the condition of abrasive wear, there exists a critical rotation speed (360 r/min) leading to a shift in the wear mechanism of UHMWPE and obtaining the lowest wear rate of about 8.49 × 10−6 mm3/N•m. At below critical rotation speed, three‐body abrasive wear and adhesive wear mainly occur in UHMWPE; And at above critical rotation speed, the wear mechanism is mainly the plowing effect of particles on the material, and the furrow width can reach 40 μm. It is believed that this study can help to improve the understanding of the wear mechanism of UHMWPE, which can support the enhancement modification of the material and the application in complex environment.

“…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.

The coefficient of friction (CoF) between the deflection pulley and rope in a lift strongly affects the life span of the rope. Although surface roughness is a key factor affecting the metallic pulley–rope CoF, its effect on polymeric pulleys is unknown. The present study analyses the effect of roughness and working conditions on cast polyamide 6 (PA6G) deflection pulley–thermoplastic polyurethane (TPU)-coated rope contacts. The statistical analysis revealed that the effect of surface roughness on the CoF for low-load tests was significant. The present study contributes significantly to parameter selection in deflection pulley machining to minimise friction between the pulley and rope.
