Résumé

The extensive use of appropriate coatings to improve wear resistance, friction coefficient, electrical properties, corrosion resistance and biomedical application has stimulated a growing interest in their mechanical properties and especially hardness testing that is routinely used for coating evaluation. In this study Jönsson and Hogmark model is applied for the porous hydroxyapatite produced by plasma spraying on Ti6A14V substrate. Firstly, the effect of indentation load on hardness values of coating and substrate are studied. The modified Jönsson and Hogmark model is used to explain the composite hardness behavior and the effect of coating porosity.

Surface degradation and cracking of dense hydroxyapatite were evaluated through Vickers micro indentation using indentation loads ranged from 25 gf to 2000 gf. Crack lengths, imprint diameters and the number of ...
MESURE DE LA TENACITE DE L’HYDROXYAPATITE PAR INDENTATION

Communication avec acte

BEHNAMGHADER, Aliasghar; NAJJAR, Denis; IOST, Alain (societe française de métallurgie et de matériaux, 2006)

L’objectif de cette étude est de caractériser le comportement fragile de l’hydroxyapatite (HAP) par évaluation de sa ténacité. Cette ténacité a été estimée pour des d’échantillons sous forme massive et pour des revêtements ...
Mechanical behavior study of plasma sprayed hydroxyapatite coatings onto Ti6Al4V substrates using scratch test

Article dans une revue avec comité de lecture

BEHNAMGHADER, Aliasghar; NAJJAR, D.; IOST, Alain; BENAYOUN, Stéphane (Trans Tech Publications Inc, 2010)

Mechanical behavior and fracture mechanisms of plasma sprayed hydroxyapatite coatings on Ti-6Al-4V substrate were assessed taking into consideration two variables: the coating thickness and the substrate roughness. The ...
A multi-scale approach of roughness measurements: Evaluation of the relevant scale
