Shaving articles formed from geometrically articulated amorphous metal alloys and processes for their production

Abstract

The invention relates to a shaving article formed of geometrically articulated amorphous metal alloy articles and processes for their production.

What is claimed is:  
     
         1 . A shaving article which comprises an amorphous metal alloy article having an articulated topographical definition.  
     
     
         2 . A shaving article according to  claim 1  comprising a plurality of articulated topographical definitions.  
     
     
         3 . A shaving article according according to  claim 1  which comprises a plurality of geometrically repeating articulated topographical definitions.  
     
     
         4 . A shaving article according having an articulated topographical definition wherein the amorphous metal alloy has a composition which may be represented by the formula: 
       M k Y p   
       wherein: 
 M is a metal selected from one or more of the group consisting of Fe, Ni, Co, V and Cr;  
 Y represents one or more elements from the group consisting of P, B and C;  
 k represents atomic percent, and has a value of from about 70-85;  
 p represents atomic percent, and has a value of about 15-30;  
 
     
     
         5 . A shaving article according having an articulated topographical definition wherein the amorphous metal alloy has a composition which may be represented by the formula: 
       M a Y b Z c   
       wherein: 
 M is a metal selected from one or more of the group consisting of Fe, Ni, Co, V and Cr;  
 Y represents one or more elements from the group consisting of P, B and C;  
 Z is one or more elements selected from the group Al, Si, Sn, Ge, In, Sb or Be;  
 a represents atomic percent and has a value of from about 60-90;  
 b represents atomic percent and has a value of from about 10-30;  
 c represents atomic percent and has a value of from about 0.1-15;  
 and, a+b+c=100.  
 
     
     
         6 . A process for the manufacture of a shaving article having an articulated topographical definition which comprises the steps of: 
 heating an amorphous metal alloy article to an elevated temperature and subsequently stamping or otherwise deforming the heated amorphous metal alloy article in a die.    
     
     
         7 . The process according to  claim 6  wherein the die is preheated.  
     
     
         8 . The process according to  claim 6  wherein the die is a roller die or a stamping die.  
     
     
         9 . The process according to  claim 6  wherein at last part of the articulated topographical definitions are selectively crystallized.  
     
     
         10 . The process according to  claim 6  wherein at last part of the articulated topographical definitions are ground to remove a part of the articulated topographical definitions.
