COMPOSITE BODIES AND METHODS OF FORMING THE SAME |
| 摘要 |
A composite body is provided that can include abrasive grains and at least one pore within a bond matrix, the abrasive grains including cubic boron nitride (cBN) and the bond matrix including a polycrystalline ceramic phase. The bonded abrasive may have a Modulus of Rupture (MOR) of not less than about 40 MPa. Certain embodiments may have porosity, such as, greater than about 5.0 vol %. |

1. A composite body comprising:
a bond material comprising a ceramic material; and a pore within the ceramic material; wherein a region of the bond material at a surface of the pore defines a first pore defining composition distinct from a composition of the ceramic material, the first pore defining composition having a melting point not less than a melting point of the composition of the ceramic material. |
