Methods for orienting superabrasive particles on a surface and associated tools
First Claim
Patent Images
1. A method of making a superabrasive tool precursor, comprising:
- (a) placing a layer of a viscous medium on a surface of a substrate, said viscous medium having a density and a viscosity;
(b) distributing superabrasive particles on the layer of viscous medium; and
(c) heating the viscous medium to decrease its viscosity, so that the superabrasive particles move at least partially through the viscous medium toward the substrate, during which the superabrasive particles are free to rotate,wherein the viscosity is selected to affect the percentage of superabrasive particles exhibiting the same orientation; and
a percentage of from 65% to about 85% of the superabrasive particles exhibit substantially the same orientation when they come to rest.
