Abstract

An abrasive article includes a substrate having an elongated body, a plurality of discrete tacking regions defining a discontinuous distribution of features overlying the substrate, where at least one discrete tacking region of the plurality of discrete tacking regions includes a metal material having a melting temperature not greater than 450° C., a plurality of discrete formations overlying the substrate and spaced apart from the plurality of discrete tacking regions, and a bonding layer overlying the substrate, plurality of discrete tacking regions, and plurality of discrete formations.

First claim

What is claimed is:

1. An abrasive article comprising:
a substrate comprising an elongated body;
a plurality of discrete tacking regions defining a discontinuous distribution of features overlying the substrate, wherein at least one discrete tacking region of the plurality of discrete tacking regions comprises a metal material having a melting temperature not greater than 450° C.;
a plurality of discrete formations overlying the substrate and spaced apart from the plurality of discrete tacking regions; and
a bonding layer overlying the substrate, plurality of discrete tacking regions, and plurality of discrete formations,
wherein at least one of the discrete tacking regions of the plurality of discrete tacking regions comprises a solder material, and
wherein the solder material comprises tin.

2. The abrasive article of claim 1 , wherein the solder material consists essentially of tin.

3. The abrasive article of claim 1 , wherein at least one of the discrete formations of the plurality of discrete formations comprises a metal material.

4. The abrasive article of claim 1 , wherein the substrate comprises a metal wire having at least one barrier layer overlying an exterior surface, wherein the barrier layer comprises a metal selected from the group of copper, brass, nickel or a combination thereof.

5. The abrasive article of claim 1 , wherein the bonding layer comprises a material selected from the group of materials consisting of metals, metal alloys, cermets, ceramics, composites, and a combination thereof.

6. An abrasive article comprising:
a substrate comprising an elongated body;
a plurality of discrete tacking regions comprising a metal material overlying the substrate, wherein at least one discrete tacking region is isolated from another discrete tacking region, and at least one abrasive particle is associated with each discrete tacking region;
a plurality of discrete formation overlying the substrate and spaced apart from the plurality of discrete tacking regions; and
a bonding layer overlying the plurality of discrete tacking regions, the at least one abrasive particle and in direct contact with at least a portion of the substrate,
wherein at least one of the discrete tacking regions of the plurality of discrete tacking regions comprises tin.

7. The abrasive article of claim 6 , wherein the plurality of discrete tacking regions include a metal material having melting temperature not greater than 450° C.

8. The abrasive article of claim 6 , wherein the solder material consists essentially of tin.

9. The abrasive article of claim 6 , wherein at least one of the discrete formations of the plurality of discrete formations comprises a metal material.

10. The abrasive article of claim 6 , wherein the substrate comprises a metal wire having at least one barrier layer overlying an exterior surface, wherein the barrier layer comprises a metal selected from the group of copper, brass, nickel or a combination thereof.

11. A method of forming an abrasive article comprising:
translating a substrate having an elongated body through a mixture including abrasive particles and a particulate including a tacking material;
attaching at least a portion of the abrasive particles and particulate to the substrate; and
treating the substrate to form an abrasive article preform including:
a plurality of discrete tacking regions overlying the substrate and defining gap regions between each of the discrete tacking regions of the plurality of discrete tacking regions;
abrasive particles overlying the plurality of discrete tacking regions; and
a plurality of discrete formations overlying the substrate and spaced apart from the plurality of discrete tacking regions and the abrasive particles,
wherein at least one of the discrete tacking regions of the plurality of discrete tacking regions comprises tin.

12. The method of claim 11 , wherein the mixture includes at least 5 wt % and not greater than 80 wt % of the abrasive particles for the total weight of the mixture.

13. The method of claim 11 , wherein the mixture includes at least 0.2 wt % to not greater than 20 wt % of the particulate including the tacking material for the total weight of the mixture.

14. The method of claim 11 , wherein the abrasive particles have an average particle size (PSa) within a range including at least 2 microns and not greater than 80 microns.

15. The method of claim 11 , wherein the particulate comprises an average particles size (PSp) within a range including at least 0.01 microns and not greater than 25 microns.
