Tribocorrosion of Diamond Like Carbon (DLC) coatings for biomedical applications
Sanchez Adam, Jorge (Master thesis, 2015)Tribocorrosion has arisen as one of the most important material degradation processes in biomedical applications; thus, the improvement of the materials used in hip or knee prosthesis is very relevant. The aim of this ... -
Triboelectrochemical friction control of W- and Ag-doped DLC coatings in water-glycol with ionic liquids as lubricant additives
Khanmohammadi, Hamid; Wijanarko, Wahyu; Cruz, Sandra; Evaristo, Manuel; Espallargas, Nuria (Peer reviewed; Journal article, 2022)In the last years, diamond like carbon (DLC) coatings doped with both carbide forming and non-carbide forming metallic elements have attracted great interest as novel self-lubricating coatings. Due to the inherent properties ... -
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. ... -
Tribological Performance of Polymers and Lubricants Used in Offshore Compensating Hydraulic Cylinders
Skjerstad, Peter (Master thesis, 2014)The direct-acting (N-line) riser tensioning system is a commonly selected option for riser tensioning on offshore deepwater drilling vessels. As the system operates in the splash zone, it is exposed to a corrosive environment ... -
Tribological Testing of Environmentally Acceptable Lubricants for Maritime Applications
Moholt, Harald (Master thesis, 2016)In marine applications, such as ship stabilizers, manoeuvring or propulsion systems, a number of mechanical components are situated below the waterline. Due to negative effects of lubricant leakage in marine environments, ... -

Leiknes, Børge Pedersen; Kvandal, Even; Kosmo, Martin Hallvard (Bachelor thesis, 2021)Abstract will be available on 2024-07-01 -
Tribologisk/material teknologisk studie: Anvendelse av Termisk Sprøytet ThermaSiC som Slitasjebelegg
Gundersen, Markus Lillebø; Veiberg, Nikolas Døving (Bachelor thesis, 2020)Abstract will be available on 2023-06-20 -
Tribology Mechanisms in Low-Friction Hardbanding Coatings.
Høgsand, Øystein Hurtig (Master thesis, 2013)As the shallow and easily accessible oil and gas reservoirs are becoming depleted, the oil and gas industry has turned its attention towards the deeper and more remote reservoirs. The increased drilling depth, more complex ... -

Wear and corrosion properties of steels used in Tunnel Boring Machines
Grødal, Christian Kreyberg (Master thesis, 2012)In this master thesis experiments were conducted to determine the abrasion-corrosion properties of a steel designed for TBM tunnelling. This was done by three different tests, reciprocal ball-on-plate, rubber wheel and ... -
Winter Sports Tribology - An Experimental Approach To Understanding Kinetic Friction and Equipment Performance in Speed Skating
Hjelle, Jørgen (Master thesis, 2017)Friction behaviour in the sport of speed skating has been investigated by use of a tribometer designed at NTNU. The objective was to study if the tribometer could measure relative differences within different skate blades. ... -
Yttrium Aluminum Garnet Powder Feedstock for Atmospheric Plasma Spray
Valaker, Emil Andre; Mubarok, Fahmi; Espallargas, Nuria (Peer reviewed; Journal article, 2020)High demands for higher turbine efficiency bring attention to newer and more advanced insulating materials for the high temperature components in the turbine. Yttrium aluminum garnet (YAG) has shown good insulating properties ...
