Abstract

An exemplary plow includes a moldboard having a wear surface and a blade having a wear surface. A wear resistant coating is applied to at least a portion of at least one of the wear surfaces of the blade and moldboard. The wear resistant coating includes a plurality of scales. Each scale has a leading edge, a trailing edge, a raised portion disposed between the leading edge and the trailing edge, and a peak of the raised portion disposed closer to the trailing edge than the leading edge. The scales of the wear resistant coating are arranged in a plurality of rows, and gaps formed between scales in one row are offset from gaps formed between scales in an adjacent row.

Claims (35)

1. A plow comprising:

a moldboard having a wear surface;

a blade having a wear surface; and

a wear resistant coating applied to at least a portion of at least one of the wear surfaces of the blade and moldboard, the wear resistant coating comprising a plurality of scales, the scales comprising:

a leading edge;

a trailing edge;

a raised portion disposed between the leading edge and the trailing edge; and

a peak of the raised portion disposed closer to the trailing edge than the leading edge;

wherein scales of the wear resistant coating are arranged in a plurality of rows; and

wherein gaps formed between scales in one row are offset from gaps formed between scales in an adjacent row.

2. The plow of claim 1 , further comprising:

at least one guard attached to at least one of the moldboard and the blade, the guard having a wear surface;

wherein the wear surface of the at least one guard is coated with the wear resistant coating.

3. The plow of claim 2 , wherein the at least one guard comprises a shoe attached to a bottom portion of the moldboard.

4. The plow of claim 1 , wherein the wear resistant coating is formed of at least one of hardened steel, carbide, tungsten, ceramic, hard-surfacing wire, nano-structures, and a bonding agent.

5. The plow of claim 1 , wherein the wear resistant coating comprises a self-healing material.

6. The plow of claim 1 , wherein the wear resistant coating has a hardness in a range of about 40 Rockwell C to about 80 Rockwell C.

7. The plow of claim 1 , wherein the wear resistant coating has a thickness in a range of about 0.0001 inches to about 2 inches.

8. The plow of claim 1 , wherein the wear resistant coating has a thickness in a range of about 0.12 inches to about 1 inch thick.

9. The plow of claim 1 , wherein the wear resistant coating is formed of a plurality of layers.

10. The plow of claim 9 , wherein each of the plurality of layers comprises a plurality of scales.

11. The plow of claim 9 , wherein a first material of at least one of the plurality of layers is different from a second material of at least another of the plurality of layers.

12. The plow of claim 9 , wherein more than one of the plurality of layers is disposed at an outer surface of the wear resistant coating.

13. The plow of claim 9 , wherein at least one of the plurality of layers is a partial layer.

14. The plow of claim 1 , wherein:

the peak of each scale comprises a contact zone; and

a total contact area of all of the contact zones comprises about 10% to about 50% of a total surface area of the wear resistant coating.

15. The plow of claim 1 , further comprising a friction reducing layer disposed on an external surface of the wear resistant coating.

16. The plow of claim 1 , wherein:

the trailing edge of each scale comprises a point; and

a length of the scale is greater than a width of the scale.

17. The plow of claim 1 , wherein:

the trailing edge of each scale comprises a plurality of lobes;

each scale further comprises a plurality of peaks; and

each peak is aligned with a lobe of the trailing edge.
