MXene@BN Heterostructures Supported Polytetrafluoroethylene Coatings for Superior Friction Performance in Hydrothermal Environments

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Mechanical dynamic sealing components are usually subjected to the erosion of a hydrothermal environment; thus, the selected service materials must meet stringent requirements for superior self‐lubrication, corrosion resistance, and thermal stability.

Self-repairing performance of wear-reduction serpentine-reinforced iron composites based on orthogonal experiments

Materials & Design
Self-repairing materials can effectively heal early-stage micro-damage; however, their performance is strongly governed by thermo-mechanical conditions during friction.

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.

Investigation of the influence of substrate hardness on the tribological performance of graphene oxide solid lubricant coatings

Friction
This study explores the impact of substrate hardness on the tribological properties of graphene oxide (GO) solid lubricant coatings on NiP alloy layers coated Q235 steel. Through adjustment of electroless plating parameters, NiP alloy layers with varying

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.

Towards optimum additive performance: A numerical study to understand the influence of roughness parameters on the zinc dialkyldithiophosphates tribofilm growth

, 2021
In recent years, several theoretical models to predict the triboreactive film thickness of zinc dialkyldithiophosphates (ZDDP) have been developed. Although these models are not complete and are approximate in nature, they provide a framework which can ...
