| 20090269151 | UNCOATED CUTTING TOOL USING BRAZED-IN SUPERHARD BLANK - An uncoated cutting tool that comprises a body containing a pocket. A polycrystalline cubic boron nitride blank has a cutting tip. The blank is brazed into the pocket using a braze alloy whereby there is a braze joint between the body and the polycrystalline cubic boron nitride blank. The braze alloy has a liquidus temperature of at least about 900 degrees Centigrade wherein the braze alloy is selected from the group comprising a nickel-gold braze alloy containing nickel and gold, a copper-gold braze alloy containing copper and gold, a silver-titanium braze alloy containing silver and titanium, and a silver-palladium braze alloy containing silver and palladium. | 10-29-2009 |
| 20100255199 | ALUMINA COATING, COATED PRODUCT AND METHOD OF MAKING THE SAME - A method of coating a substrate that includes the steps of: applying by chemical vapor deposition at a temperature ranging between about 750 degrees Centigrade and about 920 degrees Centigrade an alpha-alumina coating layer wherein the alpha-alumina coating layer exhibits a platelet grain morphology at the surface thereof. | 10-07-2010 |
