• Effect of Contamination on the Friction and Wear of Carboxylic Acids in Aqueous Lubricants 

      Bernat, Szymon Czeslaw; Armada Nieto, Sergio; Espallargas, Nuria (Peer reviewed; Journal article, 2018)
      The friction and wear mechanisms of water-based fluids consisting of various types of carboxylic acids have been systematically investigated using a ball-on-disc tribometer on a super duplex stainless steel under boundary ...
    • Environmentally Acceptable Lubricants for Stern Tube Application: Shear Stability and Friction Factor 

      Večeř, Marek; Stavárek, Petr; Krčková, Simona; Zelenka, Ladislav; Armada Nieto, Sergio (Peer reviewed; Journal article, 2024)
      Stern tube lubricants are essential in maritime operations, safeguarding ship propeller shafts from wear and corrosion while ensuring efficient propulsion. Their role in reducing friction and maintaining system integrity ...
    • Friction Mechanisms by Carboxylic Acids in Aqueous Lubricants 

      Bernat, Szymon Czeslaw; Armada Nieto, Sergio; Espallargas, Nuria (Peer reviewed; Journal article, 2018)
      Carboxylic acids are well known for their friction-reducing abilities driven by the formation of low-shear-strength films on the steel surface. However, understanding of the adsorption mechanisms especially in polar solvents ...
