AMITAVA GHOSH, D.RAGHAVA SIMHAN and PRITHVIRAJ MUKHOPADHYAY have published for grant of patent for an invention for brazing cubic boron nitride (cBN) with metal substrates. The invention proposes formulation of eutectic composition of Ag-Cu alloy by separate additions of small weight percentages of active element in the form of TiH2 along with hard ceramics (micro-alumina or micro TiN or micro TiB2 particles). An Independent addition of each type of ceramic particles aids in high wear resistance without affecting the joining ability.
