ABSTRACT:
An abrasive material is formed by coating a substrate with an adhesive, contacting he substrate with a quantity of hard, abrasive particles, then removing all particles not held by the adhesive. The remaining particles are surrounded with a sinterable or fusible material while the particles are temporarily held. The substrate can have the adhesive applied in a pattern, or covering uniformly and masked, to cause particles to adhere in certain areas to achieve a desired pattern. While the particles are held on the substrate, physical force can be applied to orient the particles uniformly; then, a powder can be applied, or the substrate can be applied to a preform. Subsequent treatment with heat and/or pressure will complete the abrasive material.
