Journal ArticleDOI
Effect of plasma interface treatment on the microstructure, residual stress profile, and mechanical properties of PVD TiN coatings on Ti-6Al-4V substrates
E.J. Herrera-Jimenez,Etienne Bousser,Thomas Schmitt,Jolanta E. Klemberg-Sapieha,Ludvik Martinu +4 more
TL;DR: In this article, the influence of the plasma pre-treatments on the microstructure, mechanical properties, especially residual stress (RS) and adhesion, of TiN coatings on Ti-6Al-4V substrates was investigated.
Journal ArticleDOI
Influence of internal stress in optical thin films on their failure modes assessed by in situ real-time scratch analysis
TL;DR: In this paper, the authors present a real-time approach to perform and analyze scratch tests of transparent coating/substrates systems, which allows for the observation of the contact region during the scratching process.
Book ChapterDOI
Modification of Polymer Surfaces by Dual Frequency Plasma
TL;DR: In this paper, the surface modifications were performed in pure microwave (MW, 245 GHz) or in combined microwave/radiofrequency (MW/RF, 245GHz/1356 MHz, “dual-frequency”) plasma diagnostics using electrostatic probes has demonstrated intense surface bombardment by energetic ions in the MW/RF case.
Journal ArticleDOI
Evidence of valence band perturbations in GaAsN/GaAs(001): Combined variable-angle spectroscopic ellipsometry and modulated photoreflectance investigation
S. Turcotte,Stéphane Larouche,J.-N. Beaudry,Ludvik Martinu,Remo A. Masut,Patrick Desjardins,Richard Leonelli +6 more
TL;DR: In this article, the contribution of the fundamental gap and its contribution to the optical and dielectric transition of the GaAs alloys were determined from variable-angle spectroscopic ellipsometry and modulated photoreflectance spectroscopy analyses.

Hydrogel attached to backing and method for making same
Faure Marie-Pierre,Jean-François Brisson,Ludvik Martinu,Jolanta E. Klemberg-Sapieha,Oleg Zabeida +4 more
TL;DR: In this article, a method of making a preformed hydrogel attach to a polymer backing comprising exposing a surface of the backing to an activated gas and depositing the preformed hydragel on the exposed surface of a polyamide backing was presented.
