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.
Claims21
An article of manufacture, comprising:
- a quasicrystalline metal alloy film less than about 10,000 Å thick, said film having a composition of a general formula AlaCubFecXdIe, where X represents one or more optional alloy elements and I represents manufacturing impurities, and where a=100−b−c−d−e;
- 24<b<26;
- 12<c<13;
- 0<d<10;
- and 0<e<3.
An article of manufacture comprising:
- a quasicrystalline AlCuFe alloy film less than about 10,000 Å thick, formed by depositing, in sequence on a substrate through radio frequency sputtering, respective layers containing stoichiometric amounts, respectively, of Al, Cu and Fe, and then annealing said respective layers to form said film through solid state diffusion.
