Abstract: This invention relates to a diamond non-stick surface and cooking utensils featuring such a surface, wherein the diamond non-stick surface includes a metal substrate and a diamond non-stick layer. The diamond non-stick layer, adhered to the metal substrate, comprises a metal bonding layer, multiple euhedral diamond crystals, and a gap filler. The diamond crystals are bonded to the metal substrate via the metal bonding layer. The gap filler, made from a non-stick coating, is disposed in the gaps between adjacent diamond crystals and atop the metal bonding layer, ensuring the combined average thickness of the metal bonding layer and the gap filler is less than the sieving particle size of the diamond crystals. When applied to the food-contact surfaces of cooking utensils, this diamond non-stick surface effectively prevents food from sticking to the spaces between the diamond crystals, significantly enhancing the surface's non-stick performance.

Abstract: A method for making a pad conditioner, includes: (a) providing a first substrate having a grain-mounting surface, and a plurality of diamond abrasive grains, each of which has a retained portion and a cutting portion with at least one sharp corner; (b) forming a plurality of recesses in the first substrate, each of the recesses having a sharp closed end and an enlarged open end, and diverging from the sharp closed end to the enlarged open end in a manner to have a shape corresponding to that of the sharp corner of each of the diamond abrasive grains; (c) disposing each of the diamond abrasive grains in a respective one of the recesses; (d) forming a second substrate on the grain-mounting surface of the first substrate; and (e) removing the first substrate.

Abstract: The present invention provides methods of forming high quality diamond bodies under high pressure, and the diamond bodies produced by such methods. In one aspect, a method may include for joining together a plurality of diamond segments to form a diamond body. The method may include placing the plurality of diamond segments in close proximity under high pressure in association with a molten catalyst and a carbon source, and maintaining the plurality of diamond segments under high pressure in the molten catalyst until the plurality of diamond segments have joined into a single diamond body.
