Abstract

An abrasive article includes a substrate comprising an elongated body, a first type of abrasive particle overlying the substrate, a bonding layer overlying the first type of abrasive particle, and a lubricious material overlying or integrated within the bonding layer.

First claim

What is claimed is:

1. An abrasive article comprising:
a substrate comprising a wire;
a tacking layer overlying the substrate;
a first type of abrasive particle overlying the tacking layer, wherein the tacking layer comprises a melting point of not greater than about 450° C.;
a bonding layer overlying the first type of abrasive particle and the tacking layer;
a lubricious material overlying or integrated within the bonding layer, wherein the lubricious material is in the form of discrete particles; and
a barrier layer in direct contact with a peripheral surface of the substrate.

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. The abrasive article of claim 1 , wherein the discrete particles are contained within the bonding layer.

9. The abrasive article of claim 1 , wherein the lubricious material is in direct contact with the first type of abrasive particle.

10. The abrasive article of claim 1 , wherein the lubricious material comprise a material selected from the group consisting of an organic material, an inorganic material, a natural material, a synthetic material, and a combination thereof.

11. The abrasive article of claim 1 , wherein the lubricious material comprises a polymer.

12. The abrasive article of claim 1 , wherein the lubricious material comprises polytetrafluoroethylene (PTFE).

13. An abrasive article comprising:
a substrate comprising a wire;
a tacking layer overlying the substrate consisting essentially tin;
a first type of abrasive particle overlying the tacking layer, wherein the tacking layer comprises a melting point of not greater than about 450° C.;
a bonding layer overlying at least a portion of the first type of the abrasive particle and the tacking layer; and
a lubricious material at the bonding layer, wherein the lubricious material is in the form of discrete particles and wherein the tacking layer is bonded to the surface of the substrate at a bonding region defined by an interdiffusion of elements between the tacking layer and the substrate.

14. An abrasive article comprising:
a substrate comprising a wire;
a tacking layer overlying the substrate comprising tin;
a first type of abrasive particle overlying the tacking layer, wherein the tacking layer comprises a melting point of not greater than about 450° C.;
a lubricious material overlying the substrate, wherein the lubricious material is in the form of discrete particles; and
a barrier layer in direct contact with a peripheral surface of the substrate.

15. The abrasive article of claim 14 , wherein the lubricious material is a non-continuous layer.

16. The abrasive article of claim 14 , wherein the lubricious material is in direct contact with the first type of abrasive particle.

17. The abrasive article of claim 14 , wherein the lubricious material comprise a material selected from the group consisting of an organic material, an inorganic material, a natural material, a synthetic material, and a combination thereof.

18. The abrasive article of claim 14 , wherein the lubricious material comprises a polymer.

19. The abrasive article of claim 14 , wherein the lubricious material comprises polytetrafluoroethylene (PTFE).
