  • Abrasive diamond composite and method of making thereof
    Publication number: 20030192259
    Abstract: An abrasive diamond composite formed from coated diamond particles and a matrix material. The diamonds have a protective coating formed from a refractory material having a composition MCxNy, that prevents corrosive chemical attack of the diamonds by the matrix material. The abrasive diamond composite may further include an infiltrant, such as a braze material. Alternatively, the abrasive diamond composite may include a plurality of coated diamond particles and a braze material filling interstitial spaces between the coated diamond particles. Methods of making such abrasive diamond composites are also disclosed.
    Type: Application
