Abstract
A superabrasive particle coated with a solidified coating of a molten braze alloy that is chemically bonded to the superabrasive particle, where the molten braze alloy includes a substantially less-reactive protective material, is disclosed and described. In one aspect, the molten braze alloy may coat at least about 80% of an outer surface of the superabrasive particle. Various methods for making and using such a coated superabrasive particle are additionally disclosed and described.
Claims77
A method for preserving the strength of a superabrasive particle having a braze alloy coating bonded thereto by application of the braze alloy coating in a molten state, comprising:
- protecting said superabrasive particle with a protective material that is substantially less-reactive with the superabrasive particle than the braze alloy during application of the braze alloy coating to the superabrasive particle.
A superabrasive tool precursor comprising:
- at least one superabrasive particle bonded with a braze alloy coating, said braze alloy coating including a substantially less-reactive protective material, said braze alloy coating including the substantially less-reactive protective material providing improved strength to the coated superabrasive particle as compared with the braze alloy alone.
A superabrasive tool comprising:
- a plurality of superabrasive particles bonded together with a braze alloy coating, said braze alloy coating including a substantially less-reactive protective material, said braze alloy coating including the substantially less-reactive protective material providing improved strength to the coated superabrasive particle as compared with the braze alloy alone;
- and
- a plurality of spacer particles chemically bonded to the molten braze alloy.
