Tungsten carbide ring composition

Abstract

A powder mixture composition for forming a jewelry article is described, comprising about 20-44% by weight tungsten carbide, and one or more of titanium carbide, chromium, nickel, and molybdenum. Methods of forming a jewelry article also are described, as are formed jewelry articles.

1 . A powder mixture composition for forming a jewelry article, comprising:
 about 20-44% by weight tungsten carbide, and one or more of:   titanium carbide, chromium, nickel, and molybdenum.   
     
     
         2 . The composition of  claim 1 , wherein the powder mixture comprises about 35-44% by weight tungsten carbide. 
     
     
         3 . The composition of  claim 1 , wherein the powder mixture comprises about 18-27% by weight titanium carbide. 
     
     
         4 . The composition of  claim 1 , wherein the powder mixture comprises about 1-2% by weight chromium. 
     
     
         5 . The composition of  claim 1 , wherein the powder mixture comprises about 17-21% by weight nickel. 
     
     
         6 . The composition of  claim 1  wherein the powder mixture comprises about 5-7% by weight molybdenum. 
     
     
         7 . The composition of  claim 1 , comprising about 35-44% by weight tungsten carbide; about 18-27% by weight titanium carbide; about 1-2% by weight chromium, about 17-21% by weight nickel, and about 5-7% by weight molybdenum. 
     
     
         8 . The composition of  claim 1 , comprising about 44% by weight tungsten carbide; about 27% by weight titanium carbide; about 1% by weight chromium, about 21% by weight nickel, and about 7% by weight molybdenum. 
     
     
         9 . The composition of  claim 1 , further comprising a rubber material. 
     
     
         10 . The composition of  claim 1 , further comprising a rubber material comprising styrene-butadiene-styrene (SBS). 
     
     
         11 . A method of forming a jewelry article comprising:
 providing a powder mixture composition comprising about 20-44% by weight tungsten carbide and one or more of titanium carbide, chromium, nickel, and molybdenum;   optionally, placing the powder mixture composition into a mold; and   applying sufficient pressure and/or temperature to the powder mixture composition to form a solid jewelry article.   
     
     
         12 . The method of  claim 11 , wherein the mold comprises a cavity having an annular configuration. 
     
     
         13 . The method of  claim 11 , further comprising the step of adding a rubber material to the powder mixture composition. 
     
     
         14 . A jewelry article formed according to the method of  claim 11 .
