Abstract
A method for forming a carbide composite that includes providing a mixture of carbide particles and a metallic binder in a container; sintering the container contents at a first processing condition having a pressure of less than about 45,000 psi; and sintering the container contents at a second processing condition having a pressure of greater than about 100,000 psi is disclosed.
Claims21
A method for forming a carbide composite, comprising:
- providing a mixture consisting of metal carbide particles and a metallic binder in a container;
- sintering the container contents at a first processing condition having a pressure of less than about 45,000 psi to form a cermet of the metal carbide particles surrounded by the metallic binder;
- and
- sintering the container contents consisting of the cermet at a second processing condition having a pressure of greater than about 500,000 psi.
