Surface interaction of grit particles and the influence of microstructure on the abrasion of cermets Universiteit Gent
Surface plastic flow of three-dimensional printed polylactic acid in the tribological study of surface patterned polymer Universiteit Gent
The potential of three-dimensional (3D) printing in polymer tribology is poorly explored. Material alignment and composition play vital roles in altering the friction and wear characteristics of 3D printed materials. In the current study, 3D patterns made by fused deposition modelling are used to print advanced tribo-composites. Two different surface patterns (line and circular) are provided through 3D printing using white and silver polylactic ...
Tribological investigation of abrasion resistant steels with martensitic and retained austenitic microstructure in single- and multi–asperity contact Universiteit Gent
Steel making companies are developing new steels with complex microstructure to satisfy abrasion resistance issues. Three newly developed steels (fresh martensitic, tempered martensitic and a TRIP steel) were investigated under single and multi-asperity abrasion test conditions. Abrasive performance was linked to material properties. In the multi-asperity test, increasing the normal load and abrasive particle size resulted in increasing mass ...

Fabrication of microporous coatings on titanium implants with improved mechanical, antibacterial and cell-interactive properties Universiteit Gent
The success of an orthopedic implant therapy depends on successful bone integration and the prevention of microbial infections. In this work, plasma electrolytic oxidation (PEO) was performed to deposit TiO2 coatings enriched with Ca, P, and Ag on titanium to improve its surface properties and antibacterial blasts efficacy while maintaining normal biological functions and thus to enhance the performance of orthopedic implants. After PEO ...
Microstructural investigation and machining performance of NbC-Ti(C0.5N0.5) matrix cermets Universiteit Gent KU Leuven
In this study, Ni or Co + Ni bonded NbC matrix cermets with secondary carbides (Mo2C and WC) as well as Ti(C0.5N0.5) were prepared by liquid phase sintering at 1450 degrees C in vacuum. Detailed microstructural investigation was performed by SEM, EPMA and XRD analysis. The microstructure, mechanical properties as well as the C45 (HB140) steel turning performance of the cermets were investigated, and compared with a commercial Ti(C0.5N0.5) based ...
