Topic X: Poster Session


Reactive multilayer systems (RMS) have been thoroughly investigated thanks to its reactant properties and to their application as heat sources for soldering and as igniters [1,2]. Typically formed by two materials, most of the studies dealing with the self-propagated reaction of these RM focused on the influence of composition, bilayer thickness ratio, and deposition parameters however, the influence of the topology of the substrate remains mostly unexplored [2]. Just recently the relationship between propagation of the reaction and the surface morphology of the substrate has been unraveled showing their potential as nonthermal interface for chip mounting [3]. Therefore, this phenomenology calls for systematic studies to understand and predict the behavior of structured reactive multilayers. Besides, RMS in the shape of free-standing foils present a high technological interest due to its versatility for localized soldering, and also because they promote a self-sustaining reaction preventing heat transfer into a substrate via conduction [2,5].

 

In this this work we present the fabrication of a free-standing structured RMS capable of generating a self-propagating reaction and study the influence of the morphology on its thermo-physical properties. For that purpose, reactive Ni/Al multilayers of 5 µm total thickness with a bilayer thickness of 100 nm were produced by magnetron sputtering using a cluster system (CS400 by ARDENNE). To obtain structured and oriented foils, the multilayers were deposited on a laminated copper substrate which was subsequently removed by using a solution of ammonium peroxydisulfate leading to free standing structured multilayers. The analysis of the morphology revealed that the topology of the copper substrate was replicated on the foils.

 

In order to study the influence of the structuring in the self-propagating reaction, samples were ignited towards different directions of the pattern by spark ignition. A high-speed camera was used to determine the velocity of the reaction and a pyrometer to record the temperature of the ignition. We have found that the orientation of the replicated structuring of the films affects the propagation of the reaction and its velocity. Therefore, the structural features transmitted from the substrate to the films can be tuned to tailor not only the path but also the velocity and temperature of the reaction in self-standing RMS.
