Claim 0:
1. A method for manufacturing a metal based component comprising at least one protrusion, said method comprising:
providing a metal based substrate comprising a surface having at least one cavity;
providing a metal based protrusion element comprising a first portion and a second portion, wherein said first portion has a shape that conforms to a shape of the cavity;
arranging the first portion of the protrusion element in said cavity such that at least the second portion of the protrusion element protrudes at least 5 mm from the surface of the metal based substrate, to form a substrate comprising a protrusion;
placing said substrate comprising the protrusion in a canister such that a void is formed between the canister and the surface of the substrate comprising the protrusion;
filling at least a portion of the void with a diamond powder such that the surface of the substrate comprising the protrusion is covered by the diamond powder;
removing gas from the interface between said diamond powder and said substrate comprising the protrusion;
subjecting said substrate comprising the protrusion to a hot pressing process for a predetermined time at a predetermined pressure and a predetermined temperature such that said substrate and protrusion element bond metallurgically to each other to form said metal based component comprising said at least one protrusion; and
removing at least a part of said diamond powder from said metal based component having a protrusion;
wherein the melting point of the diamond powder at said predetermined pressure is higher than said predetermined temperature.
