Investigating Tribological Processes in Polymeric Composites

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2011
The paper presents some results on investigation of the superficial layers of several polymeric composites intended for tribological applications. The evaluation of the tribological behavior is done with the help of SEM images, virtual images obtained by

Data set for determination of lubrication film thickness and lubrication state between bone and Ti–6Al–4V interface under three biolubrications

Data in Brief, 2019
The lubrication states between the friction pairs in lubrications have an important effect on its tribological behavior. Therefore, the aim of this complementary data article is to identify the corresponding lubrication states between bone and Ti–6Al–4V ...

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

A Strategic Approach to Improving Interfacial Interactions in TPU/POSS Composites via Ball Milling of POSS

Polymer Engineering &Science, EarlyView.
Ball‐milling promotes uniform POSS dispersion in the TPU matrix, markedly improving the mechanical performance of TPU‐POSS composites. ABSTRACT We synthesized TPU/POSS composites through a two‐step process involving the ball milling of POSS to reduce its particle size, followed by in situ polymerization of TPU to reinforce the material.

Derivatization, Characterization, and Tribological Behavior of an Amine-Terminated Polymer Surface

, 2004
The derivatization, characterization, and micro-tribological behavior of an amine-terminated polymer surface were investigated. Thus, the heptafluorobutyric anhydride (HFBA) derivatized film was characterized by means of contact-angle measurement and X ...

In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

Polymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

Tribology and Dentistry: A Commentary

Lubricants, 2019
Since 1966 the term “tribology” has integrated different topics like friction, lubrication and wear. After a few years, interest in this type of phenomena rapidly spread out around the world of biology and medicine, determining a new research
