Earth-Boring Bit Parts Including Hybrid Cemented Carbides And Methods Of Making The Same

US Patent:
2013003, Feb 14, 2013
Filed:
Oct 16, 2012
Appl. No.:
13/652508
Inventors:
TDY Industries, LLC - Pittsburgh PA, US
Prakash K. Mirchandani - Houston TX, US
Assignee:
TDY INDUSTRIES, LLC - Pittsburgh PA
International Classification:
B29C 43/02
US Classification:
264118, 264122
Abstract:
An earth-boring bit part such as, for example, a bit body, roller cone, or mud nozzle includes a hybrid cemented carbide composite. The hybrid cemented carbide includes a cemented carbide dispersed phase, and a cemented carbide continuous phase. A method of manufacture also is disclosed.

Low Density, Nonmagnetic And Corrosion Resistant Cemented Carbides

US Patent:
5736658, Apr 7, 1998
Filed:
Jul 12, 1995
Appl. No.:
8/501485
Inventors:
Prakash K. Mirchandani - Allison Park PA
Les Kastura - Detroit MI
Assignee:
Valenite Inc. - Madison Heights MI
International Classification:
C22C 2902
US Classification:
75236
Abstract:
A resilient and corrosion and wear resistant component of tooling preferably used in the deep-drawing of aluminum and steel cans is disclosed. The tooling is comprised of a distinctive nickel-bonded cemented carbide having a density less than 13 grams per cubic centimeter, a hardness of at least 88 R. sub. a, a minimum transverse rupture strength of 250,000 p. s. i. and exhibiting essentially non-magnetic behavior. Preferred compositions for the material of the tooling are also given.

Multiple Grade Cemented Carbide Articles And A Method Of Making The Same

US Patent:
5543235, Aug 6, 1996
Filed:
Apr 26, 1994
Appl. No.:
8/233388
Inventors:
Prakash K. Mirchandani - Allison Park PA
Robert E. Thomas - Beaver Falls PA
Mark Cippel - Ford City PA
Assignee:
SinterMet - Kittanning PA
International Classification:
B22F 312
B22F 706
US Classification:
428547
Abstract:
The present invention provides multiple grade, composite cemented carbide articles and a method of making such articles. The cemented carbide articles comprise carbides of different grades (or different compositions and/or microstructures) and, therefore, correspondingly different properties at different locations in the same article. The method of the present invention comprises filling different areas or portions of a die with metallurgical powders having different compositions and/or microstructures. The powder is then compressed as a single compact in the die cavity. The compressed compact is subsequently sintered to produce a multigrade cemented carbide article having composition and/or microstructural variations within the volume of the article.
