Abstract
Various articles of manufacture, such as electrosurgical scalpels, razor blades, and electronic components, comprise a quasicrystalline AlCuFe alloy film less than about 3000 Å thick, formed by depositing in sequence on a substrate through radio frequency sputtering a stoichiometric amount of each respective alloy material and then annealing those layers to form the film through solid state diffusion.
