Effect of Contamination on the Friction and Wear of Carboxylic Acids in Aqueous Lubricants
Bernat, Szymon Czeslaw; Armada Nieto, Sergio; Espallargas, Nuria (Journal article; Peer reviewed, 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 ... -
Friction Mechanisms by Carboxylic Acids in Aqueous Lubricants
Bernat, Szymon Czeslaw; Armada Nieto, Sergio; Espallargas, Nuria (Journal article; Peer reviewed, 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 ... -
Tribological Behavior of Polymer Seal Materials in Water-Based Hydraulic Fluids
Bernat, Szymon Czeslaw; Brink, Angelika; lucas, melodia; Espallargas, Nuria (Journal article; Peer reviewed, 2018)In this work, two polymer materials have been tested in a lubricated reciprocating pin-on-plate contact geometry using water-based hydraulic fluids to simulate sliding conditions of seal materials used in offshore equipment. ...
