Designing a High Precision Rotating and Reciprocal Tribometer
Audal, Mathias; Gusfre, Fredrik; Skjerdingstad, Jon Paulsen (Bachelor thesis, 2023)Dette prosjektet har fokusert på design og utvikling av to tribometere for høy presisjon, som er ment å bli brukt på tribologilaben ved Institutt for maskinteknikk og produksjon på NTNU. Målet har vært å bidra til det ... -
Ionic liquid additives in water-based lubricants for bearing steel – effect of electrical conductivity and pH on surface chemistry, friction and wear
Wijanarko, Wahyu; Khanmohammadi, Hamid; Espallargas, Nuria (Journal article; Peer reviewed, 2022) -
Ionic Liquids as Additives in Low Viscosity Lubricants – A Surface Adsorption and Tribofilm Study
Wijanarko, Wahyu (Doctoral theses at NTNU;2022:130, Doctoral thesis, 2022)The trend in lubrication nowadays is towards low viscosity lubricants. Low viscosity lubricants flow more easily, increasing the lubricant volume circulation thus improving the cooling performance and cleaning ability of ... -
Ionic Liquids as Additives in Water‑Based Lubricants: From Surface Adsorption to Tribofilm Formation
Khanmohammadi, Hamid; Wijanarko, Wahyu; Espallargas, Nuria (Peer reviewed; Journal article, 2020)Ionic liquids (ILs) are potential lubricant additives that can potentially perform simultaneously as friction modifiers and anti-wear agents. In addition, they possess good thermal stability, they are non-flammable, they ... -
Ionic liquids as boundary additives in water-based and PAO lubricants
Wijanarko, Wahyu; Khanmohammadi, Hamid; Espallargas, Nuria (Peer reviewed; Journal article, 2021)Ionic liquids have been widely discussed as potential lubricants, however, their properties make them also very good potential candidates as lubricant additives (e.g., friction modifiers and anti-wear). In this work, the ... -
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 ...
