WebFeb 1, 2008 · Reactive multilayers are generally fabricated using physical vapor deposition (PVD) methods, such as magnetron sputtering or electron-beam evaporation. In PVD multilayers, Ma et al. 11 performed calorimetric measurements on Ni/Al multilayer films prepared by electron-beam evaporation. Websystem selection, the stoichiometric ratio of Reactive multilayer systems (RMS) provide a precisely definable amount of heat within a few milliseconds for the gentle joining of components. They consist of several hundred periodically built-up layers from two materials with individual layer thicknesses of a few nanometers.
