Abstract
An abrasive article, comprising a polycrystalline material comprising abrasive grains and a filler material having an average negative coefficient of thermal expansion (CTE) within a range of temperatures between about 70 K to about 1500 K. A method of forming an abrasive article, comprising preparing an abrasive material, preparing a filler material having an average negative coefficient of thermal expansion (CTE) within a range of temperatures between about 150 K to about 1500 K, and forming a polycrystalline material comprising grains of the abrasive material and the filler material.
Claims16
A method of forming an abrasive article, comprising:
- preparing an abrasive material;
- preparing a filler material having an average negative coefficient of thermal expansion (CTE) within a range of temperatures between about 150 K to about 1500 K;
- forming a green body comprising the abrasive material and the filler material;
- and
- subjecting the green body to a high temperature, high pressure process to form a polycrystalline material comprising grains of the abrasive material and the filler material.
A method of forming an abrasive article, comprising:
- preparing an abrasive material;
- preparing a filler material having an average negative coefficient of thermal expansion (CTE) within a range of temperatures between about 150 K to about 1500 K, wherein preparing the filler material comprises preparing a precursor filler material, wherein preparing the filler material comprises forming a precursor filler material comprising a suspension of particles of the filler material in a liquid;
- forming a green body comprising the abrasive material and the filler material;
- and
- subjecting the green body to a high temperature, high pressure process to form a polycrystalline material comprising grains of the abrasive material and the filler material.
