Ultralow friction and wear of reciprocating systems lubricated by liquid crystalline fluids

open access: yes, 2022
S.409-416Tribological systems that are lubricated with liquid crystals exhibit ultralow friction coefficients and wear. This effect, which has not yet been well examinated and which is even less understood, has been reproducibly observed in reciprocating

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

open access: yesAdvanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Additive Manufacturing of Alumina‐Reinforced Elastomers

open access: yesAdvanced Engineering Materials, EarlyView.
Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Tribological characteristics of Al–Mg–Si–Cu alloy against die steel under elevated temperatures in simulated hot extrusion environment

open access: yesJournal of Materials Research and Technology
Friction is a considerable boundary condition in aluminum alloy hot extrusion. In this study, ball-on-disc friction tests at temperatures of 25–500 °C were performed to equivalently simulate the interface tribological behaviors between Al–Mg–Si–Cu alloy ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
