Tribological properties of novel palygorskite nanoplatelets used as oil-based lubricant additives

Friction, 2020
Layered palygorskite (PAL), commonly called attapulgite, is a natural inorganic clay mineral composed of magnesium silicate. In this study, an aqueous miscible organic solvent treatment method is adopted to prepare molybdenum-dotted palygorskite (Amo-PMo)

Synthesis and tribological testing of poly(methyl methacrylate) particles containing encapsulated organic friction modifier [PDF]

, 2018
The tribological behaviour of polymer particles containing an encapsulated, organic friction modifier (FM) is presented. Particles comprising of a poly (methyl methacrylate) (PMMA) shall and a methanol core, into which FM was dissolved, were produced via

Tribological Performance of 60NiTi Alloy Under Varying Contact Conditions and Elevated Temperatures in Linear Reciprocating Sliding

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐

Correlation between Nano-Mechanical and Macro-Tribological Properties of Tribofilms Derived from Organic Phosphoric Additives

Tribology Online, 2016
Correlation between nano-mechanical and macro-tribological properties of the tribofilm derived from phosphoric additives was investigated. Macro friction test was performed at steel/steel contact under lubrication with poly-alpha olefin (PAO) containing ...

Tribological behaviour of copper oxide nanoparticle suspension [PDF]

, 2008
This work presents and discusses the tribological behaviour of nanoparticle suspensions in a polyalphaolefin (PAO6). CuO nanoparticles were separately dispersed at 0.5, 1.0 and 2.0% wt. in PAO6 using an ultrasonic probe for 2 minutes.

Multiresponse Tribological Ranking Alternatives of Al–Cu Alloys via an Integrated Taguchi Experimental Design, AHP Weighting, and WASPAS Decision Framework

Engineering Reports, Volume 8, Issue 5, May 2026.
To optimize aluminium–copper alloy compositions and tribological parameters for improved wear performance using an integrated hybrid MCDM approach. The Al–Cu alloy compositions were fabricated through die casting. Their tribological performance was evaluated and optimized using a hybrid Taguchi–AHP–WASPAS methodology under varying loads, sliding speeds,

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

Polymer Composites, Volume 47, Issue 8, Page 6840-6858, 20 April 2026.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts
