<p>A ground engaging tool for an earthworking machine (2) comprises a ground engaging element (6) with a cast-in-place metal matrix composite component (8). The ground engaging element (6) comprises a metal base component (7) and a metal matrix composite component (8). The metal matrix component (8) is bonded to the metal base component (7). The metal matrix composite component (8) consists of a preform (10) having interconnecting porosity. The preform (10) is formed from a material selected from one of ceramic, cermet, or mixtures thereof. The metal matrix composite component (8) also consists of an infiltration metal (12). The preform (10) is infiltrated by the infiltration metal (12) and the infiltration metal (12) is fusion bonded to the metal base component (7).</p> |
