Wear component for compactor wheel

Abstract

A wear component includes a base portion and a tip portion. The tip portion includes a proximate end and a distal end. The proximate end is metallurgically bonded to the base portion at a base-tip interface, which may have a generally parabolic cross-sectional profile. The distal end defines an exterior surface of the wear component.

What is claimed is: 
     
         1 . A wear component, comprising:
 a base portion; and   a tip portion including:
 a proximate end metallurgically bonded to the base portion at a base-tip interface; and 
 a distal end defining an exterior surface of the wear component, 
   wherein the base-tip interface has a generally parabolic cross-sectional profile.   
     
     
         2 . The wear component of  claim 1 , wherein:
 the base portion includes a side surface extending from the base-tip interface to a mounting end of the base portion; and   the mounting end includes a recess.   
     
     
         3 . The wear component of  claim 1 , wherein the tip portion includes an at least partially concave side surface extending from the distal end to the proximate end. 
     
     
         4 . The wear component of  claim 1 , wherein:
 the base portion is formed from a first material with a carbon-equivalent (CE) value of less than 0.7; and   the tip portion is formed from a second material with a hardness of at least 45 Rockwell C.   
     
     
         5 . The wear component of  claim 4 , wherein:
 the first material is steel; and   the second material is steel or iron.   
     
     
         6 . The wear component of  claim 5 , wherein:
 the first material is carbon steel, alloy steel, or stainless steel; and   the second material is high-chromium white iron or Ni-Hard.   
     
     
         7 . A wear component, comprising:
 a base portion; and   a tip portion including:
 a proximate end metallurgically bonded to the base portion at a base-tip interface; 
 a distal end defining an exterior surface of the wear component; and 
 an at least partially concave side surface extending from the distal end to the proximate end. 
   
     
     
         8 . The wear component of  claim 7 , wherein:
 the base portion includes a side surface extending from the base-tip interface to a mounting end of the base portion; and   the mounting end includes a recess.   
     
     
         9 . The wear component of  claim 7 , wherein:
 the base portion is formed from a first material with a carbon-equivalent (CE) value of less than 0.7; and   the tip portion is formed from a second material with a hardness of at least 45 Rockwell C.   
     
     
         10 . The wear component of  claim 9 , wherein:
 the first material is steel; and   the second material is steel or iron.   
     
     
         11 . The wear component of  claim 10 , wherein:
 the first material is carbon steel, alloy steel, or stainless steel; and   the second material is high-chromium white iron or Ni-Hard.   
     
     
         12 . A wear component, comprising:
 a base portion including a plurality of protrusions; and   a tip portion including:
 a proximate end metallurgically bonded to the base portion at a base-tip interface, and including a plurality of recesses; and 
 a distal end defining an exterior surface of the wear component, 
   wherein, at the base-tip interface, the plurality of protrusions extend into the plurality of recesses.   
     
     
         13 . The wear component of  claim 12 , wherein the plurality of recesses extend from a first side of the tip portion to a second side of the tip portion opposite the first side. 
     
     
         14 . The wear component of  claim 13 , wherein each of the plurality of recesses is a rabbet in an outer edge of the tip portion. 
     
     
         15 . The wear component of  claim 12 , wherein the proximate end includes two recesses. 
     
     
         16 . The wear component of  claim 12 , wherein:
 the base portion includes a side surface extending from the base-tip interface to a mounting end of the base portion; and   the mounting end includes a recess.   
     
     
         17 . The wear component of  claim 12 , wherein the tip portion includes an at least partially concave side surface extending from the distal end to the proximate end. 
     
     
         18 . The wear component of  claim 12 , wherein:
 the base portion is formed from a first material with a carbon-equivalent (CE) value of less than 0.7; and   the tip portion is formed from a second material with a hardness of at least 45 Rockwell C.   
     
     
         19 . The wear component of  claim 18 , wherein:
 the first material is steel; and   the second material is steel or iron.   
     
     
         20 . The wear component of  claim 19 , wherein:
 the first material is carbon steel, alloy steel, or stainless steel; and   the second material is high-chromium white iron or Ni-Hard.
