Abstract

A metal powder composition for making compacted parts, the metal powder composition including (i) sponge iron particles or sponge iron-based particles, and (ii) a lubricant including at least two different fatty acid amides. A process including (i) compacting the metal powder composition, and (ii) sintering the thus obtained compacted metal powder composition to produce a metal product.

Claims

exact text as granted — not AI-modified
1 . Metal powder composition comprising (i) sponge iron particles or sponge iron-based particles, and (ii) a lubricant comprising at least two different fatty acid amides. 
     
     
         2 . Metal powder composition according to  claim 1 , wherein the lubricant comprises at least three different fatty acid amides. 
     
     
         3 . Metal powder composition according to  claim 1 , wherein at least one of the fatty acid amides is a monoamide of the formula R—C(O)—NH 2 , wherein R is a hydrocarbyl group. 
     
     
         4 . Metal powder composition according to  claim 3 , wherein at least two of the said fatty acid amides are monoamides of the formula R—C(O)—NH 2 , wherein R is a hydrocarbyl group. 
     
     
         5 . Metal powder composition according to  claim 2 , wherein said at least three different fatty acid amides are monoamides of the formula R—C(O)—NH 2 , wherein R is a hydrocarbyl group. 
     
     
         6 . Metal powder composition according to  claim 3 , wherein R is n-alkyl and contains 13 to 23 carbon atoms. 
     
     
         7 . Metal powder composition according to  claim 1 , wherein at least one of the fatty acid amides is palmitic acid amide. 
     
     
         8 . Metal powder composition according to  claim 1 , wherein the lubricant is a mixture of behenamide, stearamide and palmitamide. 
     
     
         9 . Metal powder composition according to  claim 1 , wherein component (i) of the metal powder composition is sponge iron-based particles which comprise sponge iron particles together with one or more of C, Cu, Ni and Mo. 
     
     
         10 . A process comprising (i) compacting a metal powder composition as defined in  claim 1 , and (ii) sintering the thus obtained compacted metal powder composition to produce a metal product. 
     
     
         11 . A metal product obtainable by a process as defined in  claim 10 .
