| 摘要 | 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. | ||||||
| 权利要求 | 1. A CUTTING IMPLEMENT COMPRISING A METAL WHICH IS AT LEAST 50% AMORPHOUS, CHARACTERIZED IN THAT THE METAL HAS THE COMPOSITION MAXB, 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. 2. The cutting implement of claim 1 in which a ranges from about 73 atomic percent to 84 atomic percent and b ranges from about 16 atomic percent to 27 atomic percent. 3. The cutting implement of claim 1 in the form of a razor blade. 4. A cutting implement having deposited thereon a metal film which is at least 50% amorphous, characterized in that the metal has the composition MaXb, 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. 5. The cutting implement of claim 4 in which a ranges from about 73 atomic percent to 84 atomic percent and b ranges from about 16 atomic percent to 27 atomic percent. 6.
