Abstract:
1. A track shoe for a track-type machine, the track shoe comprising: a base plate; a grouser projecting away from said base plate, said grouser including a distal edge surface facing away from said base plate, said grouser further including a first lateral face extending away from said distal edge surface and a second lateral face extending away from said distal edge surface; and a capping surface structure including a first covering segment disposed in covering relation to at least a portion of said first lateral face adjacent to said distal edge surface, and a second covering segment disposed at least partially across said distal edge surface, said capping surface structure being formed from a material characterized by enhanced wear resistance relative to portions of said grouser underlying said capping surface structure, and wherein the material forming said capping surface structure is a composite of tungsten carbide particles embedded within a ferrous metal matrix at a packing factor of not less than about 0.6 as measured by area occupancy ratio of the tungsten carbide particles within a defined measurement zone within the capping surface structure.
