Abstract
A track link for a ground-engaging track includes an elongate link body having a lower hardness material forming a lower mounting surface for mounting a track shoe, and a sacrificial higher hardness material forming an upper rail surface for contacting rotatable track engaging elements. The lower hardness and higher hardness materials transition at a material interface within the elongate link body, and the material interface is longitudinally non-uniform, such that the sacrificial higher hardness material has a varying depth from the upper rail surface to retard scalloping.
