| Résumé | The cold spray technique, historically used for metals, is increasingly being used to fabricate metal matrix composites (MMCs) and for metallization of ceramics. The quality of these materials depends on the nature of the metal/ceramic interfaces made by high speed impact. For example, the adhesion of these metal/ceramic interfaces affect the properties of MMCs, such as their wear and corrosion resistance. Here, we studied the interface of single titanium splats deposited on alumina and silicon carbide substrates. Adhesion strength is measured by a specialized splat adhesion test. The type of ceramic has a significant effect on adhesion strength and critical velocity. Surface roughness also influences adhesion and bonding mechanism in the titanium/alumina interface. Bonding on the smooth alumina substrate is associated to adiabatic shearing of the particles at impact. Bonding on the rough substrate is mainly mechanical. Interface characteristics are discussed through post-test characterization with scanning electron microscopy. |
