Wear resistant coating with scale shape

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.

 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.   
     
     
         18 . A plow component comprising:
 a wear surface; and   a wear resistant coating applied to at least a portion of the wear surface of the plow component, 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.   
     
     
         19 . The plow component of  18 , wherein the plow component is one of a plow blade, a moldboard guard, and a plow shoe.
