Method of making diamond-bonded constructions with improved thermal and mechanical properties |
摘要 |
Diamond-bonded constructions include a diamond-bonded body having a thermally stable region extending a distance below a diamond-bonded body surface. The thermally stable region comprises a matrix phase of bonded-together diamond crystals, and interstitial regions comprising a reaction product. The reaction product is formed by reaction between the diamond crystals and a reactive material. The reactant is a carbide former and the reaction product is a carbide. The diamond-bonded body includes a further diamond region extending from the thermally stable region that comprises the matrix phase and a Group VIII metal disposed within interstitial regions of the matrix phase. The thermally stable region is substantially free of a catalyst material used to initially form the diamond-bonded body. The diamond-bonded body may include a material layer formed from the reaction product that is disposed on a surface of the diamond-bonded body thermally stable region.
