Abstract

An abrasive article including a substrate having an elongated body, a tacking layer overlying the substrate, and a first type of abrasive particle overlying the tacking layer and defining a first abrasive particle concentration at least about 10 particles per mm of substrate.

First claim

The invention claimed is:

1. An abrasive article comprising:
a substrate having an elongated body;
a tacking layer overlying a surface of the substrate;
a first type of abrasive particle overlying the tacking layer, wherein the tacking layer comprises an average thickness of at least 11% and not greater than 30% of an average particle size of the first type of abrasive particles, and
a barrier layer in direct contact with a peripheral surface of the substrate; and
a bonding layer overlying the tacking layer and the first type of abrasive particle.

2. The abrasive article of claim 1 , wherein the barrier layer is disposed between the peripheral surface of the substrate and the tacking layer.

3. The abrasive article of claim 1 , wherein the barrier layer comprises a material different from the tacking layer.

4. The abrasive article of claim 1 , wherein the barrier layer comprises a non-alloyed material.

5. The abrasive article of claim 1 , wherein the barrier layer comprises an average thickness of not greater than about 10 microns.

6. The abrasive article of claim 1 , wherein the barrier layer is a dip-coating layer.

7. The abrasive article of claim 1 , wherein the barrier layer is applied at a temperature not greater than about 400° C.

8. An abrasive article comprising:
a substrate having an elongated body;
a tacking layer overlying a surface of the substrate;
a first type of abrasive particle overlying the tacking layer, wherein the tacking layer comprises an average thickness of at least 11% and not greater than 30% of an average particle size of the first type of abrasive particles, and wherein the first type of abrasive particle defines a bimodal particle size distribution;
a barrier layer in direct contact with a peripheral surface of the substrate; and
a bonding layer overlying the tacking layer and the first type of abrasive particle.

9. The abrasive article of claim 8 , wherein the bimodal particle size distribution comprises a first mode defining a first median particle size (M 1 ) and a second mode defining a second median particle size (M 2 ), wherein the first median particle size and second median particle size are at least 5% different based on the equation ((M 1 −M 2 )/M 1 )×100%.

10. The abrasive article of claim 8 , 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.

11. The abrasive article of claim 8 , wherein the bonding layer comprises a transition metal element.

12. The abrasive article of claim 8 , wherein the bonding layer comprises a metal selected from the group of metals consisting of lead, silver, copper, zinc, tin, titanium, molybdenum, chromium, iron, manganese, cobalt, niobium, tantalum, tungsten, palladium, platinum, gold, ruthenium, and a combination thereof.

13. The abrasive article of claim 8 , wherein the bonding layer comprises nickel.

14. The abrasive article of claim 8 , wherein the bonding layer comprises an average thickness of at least about 10% of an average particle size of the abrasive particle and not greater than about 90%.

15. The abrasive article of claim 8 , wherein the bonding layer comprises an average thickness of at least about 1 micron and not greater than about 50 microns.

16. The abrasive article of claim 8 , wherein the tacking layer comprises a material selected from the group of materials consisting of metal, metal alloys, metal matrix composites, and a combination thereof.

17. The abrasive article of claim 8 , wherein the tacking layer comprises a metal alloy of tin and lead.

18. The abrasive article of claim 8 , wherein the tacking layer consists essentially of tin.

19. The abrasive article of claim 8 , wherein the tacking layer comprises a solder material.
