CUTTER ASSEMBLY WITH AT LEAST ONE ISLAND AND A METHOD OF MANUFACTURING A CUTTER ASSEMBLY
First Claim
1. A method of fabricating a cutting element having at least one island structure in at least one pocket of a substrate, comprising:
- building the substrate with at least one pocket;
putting the at least one island into the at least one pocket in the substrate to form an assembly, the at least one island is not in a final state, wherein in the final state, chemical composition, shape, phase distribution and content, density and mechanical properties are finalized without changes; and
subjecting the assembly to a final fabrication process to form the said cutting element and achieve the final state of the cutting element and at least one island in at least one pocket.

Abstract
A cutter assembly and a method of making the cutter assembly are disclosed. A method of fabricating a cutting element having at least one island structure in at least one pocket of a substrate may comprise steps of building the substrate with at least one pocket; putting the at least one island into the at least one pocket in the substrate to form an assembly, the at least one island is not in a final state, wherein in the final state, chemical composition, shape, phase distribution and content, density and mechanical properties are finalized without changes; and subjecting the assembly to a final fabrication process to form the said cutting element and achieve the final state of the cutting element and at least one island in at least one pocket.
