Use Of Sn And Pore Size Control To Improve Biocompatibility In Polycrystalline Diamond Compacts
US Patent:
8449991, May 28, 2013
Filed:
Apr 10, 2009
Appl. No.:
12/422203
Inventors:
Clayton F. Gardinier - Lafayette LA, US

Assignee:
Dimicron, Inc. - Orem UT
International Classification:
B32B 9/00, B32B 19/00, B32B 5/18, B22F 3/10, B22F 3/00, B22F 5/00
US Classification:
428697, 428550, 428551, 428613, 428634, 428646, 623 1811, 623 2351, 623 2353, 623 2356
Abstract:
Polycrystalline diamond compacts for use in artificial joints achieve reduced corrosion and improved biocompatibility through the use of solvent metal formulations containing tin and through the control of solvent metal pore size, particularly in inner layers of the compact. Solvent metal formulations containing tin have been discovered which provide sintering ability, part strength, and grind resistance comparable to levels achieved by using CoCrMo solvent metals. It has been discovered that limiting the solvent metal pore size in the diamond layers minimizes or eliminates the occurrence of micro cracks in the solvent metal and significantly reduces the corrosion of the compact as manifested by the release of heavy metal ions from the compact. Polycrystalline diamond compacts which utilize both the solvent metal formulations containing tin and the control of pore sizes achieve significantly reduced corrosion and improved biocompatibility compared to prior art polycrystalline diamond compacts.

Surface Geometry For Non-Planar Drill Inserts
US Patent:
6196340, Mar 6, 2001
Filed:
Nov 28, 1997
Appl. No.:
8/980389
Inventors:
Kenneth M. Jensen - Orem UT

Assignee:
U.S. Synthetic Corporation - Orem UT
International Classification:
E21B 1056
US Classification:
175431
Abstract:
A cutting element insert is provided for use with drills used in the drilling and boring through of subterranean formations. This new insert has a modified diamond surface shape having ridges, facets and/or other discontinuities on the cutting surface topography, formed on or about an otherwise non-planar shape, such as spherical, hemispherical, conical or the like. This modified diamond layer shape provides increased cutting stress at the diamond/rock interface, thereby causing the rock to fail with less over all drilling energy being required, while simultaneously introducing little additional stresses to the cutter or insert.
