Abstract
A method of forming a corrosion resistant bushing includes bonding a sliding layer to a first surface of a load bearing substrate to form a laminate sheet and cutting a blank from the laminate sheet. The laminate sheet includes an exposed surface corresponding to a second surface of the load bearing substrate. The blank includes cut edges having a load bearing substrate portion. The method further includes forming a semi-finished bushing from the blank.
Claims18
A sliding article comprising:
- a load bearing substrate, having a first major surface, a second major surface, and an edge, the load bearing substrate having a thickness t1,
- an aluminum containing layer overlying and in direct contact with the first major surface, the aluminum containing layer having a thickness t2, wherein t2 is at least 10 microns,
- a sliding layer overlying the first or the second major surface,
- wherein a ratio of t2/t1 is at least 1/10, further comprising a functional layer comprising an elastomer layer overlying the load bearing substrate opposite the sliding layer.
