Abstract
Various articles of manufacture, such as electrosurgical scalpels, razor blades, electronic components and mechanical components having a quasicrystalline AlCuFe alloy film less than about 10,000 å thick. Such articles of manufacture may be 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.
