US Patent:

42685826, May 19, 1981

Filed:

Mar 2, 1979

Appl. No.:

6/016902

Inventors:

Thomas E. Hale - Warren MI
Roy C. Lueth - Marine City MI

Assignee:

General Electric Company - Detroit MI

International Classification:

C23C 1114
B32B 1304
B32B 3124

US Classification:

428446

Abstract:

A coated cemented carbide article comprises a cemented carbide substrate, the surface regions thereof having diffused therein an element such as boron, silicon or aluminum. The article further comprises a coating disposed on the diffused substrate, the coating being a boride such as titanium boride, hafnium boride, zirconium boride or tantalum boride. In another embodiment the coated cemented article further includes an interlayer sandwiched between the diffused substrate and the boride coating, the interlayer being one or more layers formed from the carbides, nitrides or carbonitrides of elements from groups IVb and Vb of the Periodic Table of Elements, and combinations thereof.

International Classification:

B22F 3/12
B22F 1/02

US Classification:

419 12, 419 17, 419 32

Abstract:

The present invention includes consolidated hard materials, methods for producing them, and industrial drilling and cutting applications for them. A consolidated hard material may be produced using hard particles such as BC or carbides or borides of W, Ti, Mo, Nb, V, Hf, Ta, Zr, and Cr in combination with an iron-based, nickel-based, nickel and iron-based, iron and cobalt-based, aluminum-based, copper-based, magnesium-based, or titanium-based alloy for a binder material. Commercially pure elements such as aluminum, copper, magnesium, titanium, iron, or nickel may also be used for the binder material. The mixture of the hard particles and the binder material may be consolidated at a temperature below the liquidus temperature of the binder material using a technique such as rapid omnidirectional compaction (ROC), the CERACON™ process, or hot isostatic pressing (HIP). After sintering, the consolidated hard material may be treated to alter its material properties.
