Cobalt‐Doped Diamond‐Like Carbon Coatings Combined With Functionalised Polymers for Enhanced Tribological Performance

Lubrication Science, Volume 38, Issue 4, Page 191-197, June 2026.
ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.

TGA/DTA‐Based Sintering Optimization of Al‐Graphene‐B4C Hybrid Composites and Effect on Mechanical and Tribological Behavior

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
Thermal analysis‐based (TGA/DTA) sintering provides a composition‐dependent route for optimizing Al‐graphene‐B4C hybrid composites. TGA/DTA identifies mass‐change intervals and suitable sintering temperature ranges, while XRD and SEM/EDX observations support phase and microstructural evaluation.

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‐

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
