One-piece component and method for its production

Abstract

A one-piece component includes a first subregion made of a base material, and a second subregion made of the base material as binder with intercalated hard material particles, the second subregion being injection-molded onto the first subregion by means of MIM injection molding, so that an integral connection is formed between the first subregion and the second subregion. Furthermore, a method for producing the one-piece component by means of MIM injection molding is described.

What is claimed is: 
     
         1 . A method for producing a one-piece component by means of MIM injection molding, comprising:
 injection-molding a first subregion made of a base material, and   injection-molding a second subregion made of the base material as binder and including intercalated hard material particles, onto the first subregion, such that an integral connection is formed between the first and second subregions.   
     
     
         2 . The method according to  claim 2 , wherein the base material is an austenitic or ferritic steel, which includes iron and chromium. 
     
     
         3 . The method according to  claim 2 , wherein the hard material particles are oxides, including Al 2 O 3 , ZrO 2  or Y 2 O 3 . 
     
     
         4 . The method according to  claim 2 , wherein the hard material particles are one of a) carbides, including titanium carbide, wolfram carbide, niobium carbide or tantalum carbide, or b) nitrides, including titanium nitride.
