Abstract
A manufacturing process may comprise: stacking a plurality of friction discs together, each friction disc comprising a lug defining a surface; and depositing a composition to bond to the surface of a first friction disc in the plurality of friction discs to form a wear pad defining a wear surface.
Claims17
A manufacturing process comprising:
- stacking a plurality of friction discs together, each friction disc comprising a lug defining a surface;
- texturing, via a laser beam emitted from a laser source, the surface to form a textured surface;
- and subsequently
- depositing, via a depositing step, a composition to bond to the textured surface of a first friction disc in the plurality of friction discs to form a wear pad that is bonded to the textured surface and defines a wear surface, wherein the depositing the composition includes forming a molten deposit pool via directing the laser source towards the surface and depositing a powder on the textured surface to bond the molten deposit pool thereto.

A friction disc, comprising:
- an annular structure and a plurality of lugs, each lug in the plurality of lugs extending radially from the annular structure, the plurality of lugs being spaced apart;
- and
- a plurality of wear pads, each wear pad defining a wear surface configured to interface with one of a spline, a torque bar, or a torque plate, each wear pad in the plurality of wear pads being bonded to a surface of a lug in the plurality of lugs by:
- forming a molten deposit pool via directing a laser source towards the surface, and
- depositing a powder on the surface.
