Abstract
Metal alloys in an amorphous state are employed in the fabrication of cutting implements such as razor blades or knives. The implement may be formed from the amorphous metal or a coating of the amorphous metal may be applied. Such products may be formed from a ribbon of the amorphous metal alloy which has been prepared by quenching the molten metal or by coating the amorphous metal alloy on a suitable substrate such as by a sputtering procedure or vapor, chemical or electro-deposition of the alloy on the substrate.
Claims8
In a process of preparing a metal cutting implement by shaping a metal strip into the desired implement form and sharpening a cutting edge on said implement, the improvement which comprises quenching a molten metal alloy under conditions producing the metal strip in at least 50 percent amorphous state, said metal alloy having the composition represented by M.sub.a X.sub.b, where M is at least one element selected from the group consisting of Ni, Fe, Co, Cr and V, X is at least one element selected from the group consisting of P, B, C, Si, Al, Sb, Sn, In, Ge and Be, a ranges from 65 atomic percent to 90 atomic percent and b ranges from 10 atomic percent to 35 atomic percent.
In a method of fabricating a metal cutting implement from a metal substrate by depositing a metal film on said substrate, the improvement which comprises employing a metal film which is at least 50 percent amorphous and has the composition represented by M.sub.a X.sub.b, where M is at least one element selected from the group consisting of Ni, Fe, Co, Cr and V, X is at least one element selected from the group consisting of P, B, C, Si, Al, Sb, Sn, In, Ge and Be, a ranges from 65 atomic percent to 90 atomic percent and b ranges from 10 atomic percent to 35 atomic percent.
