Abstract:
This invention relates to a double composite structure comprising cemented carbides embedded in an austenitic stainless steel matrix forming a wear, impact, drill and corrosion resistant shape by powder metallurgy techniques. Molten metal is then cast around the composite structure forming the body of a tool, lock or parts which are particularly useful for earthmoving and security applications.
