Abstract
A ground engaging tool for an earthworking machine comprises a ground engaging element with a cast-in-place metal matrix composite component. The ground engaging element comprises a metal base component and a metal matrix composite component. The metal matrix component is bonded to the metal base component. The metal matrix composite component consists of a preform having interconnecting porosity. The preform is formed from a material selected from one of ceramic, cermet, or mixtures thereof. The metal matrix composite component also consists of an infiltration metal. The preform is infiltrated by the infiltration metal and the infiltration metal is fusion bonded to the metal base component.
