Abstract:
An articulating joint includes a linkage and a pin. The linkage includes a surface defining an opening. The pin extends along a pivot axis, and is disposed, at least in-part, in the hole. The pin has a core component made of a first material, and an outer component that at least partially circumferentially surrounds the core component and is made of a wear resistant material. The outer component includes a gradated sub-surface depth extending in a radial direction.
