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.

Systems and methods for manufacturing wear pads

A method of forming an aircraft component includes providing an aluminum alloy. The method further includes mixing a shape memory alloy (SMA) with the aluminum alloy to form a combination of the SMA and the aluminum alloy. The method further includes forming the aircraft component with the combination of the SMA and the aluminum alloy.

A hybrid torque bar for a brake assembly may comprise a base portion, a pin extending from a first end of the base portion, and a rail extending between the first end of the base portion and a second end of the base portion opposite the first end. The base portion may be formed using a first manufacturing process. At least one of the pin or the rail may be formed using a second manufacturing process. The second manufacturing process may comprise an additive manufacturing technique.

A hybrid torque bar for a brake assembly may comprise a base portion, a pin extending from a first end of the base portion, and a rail extending between the first end of the base portion and a second end of the base portion opposite the first end. The base portion may be formed using a first manufacturing process. At least one of the pin or the rail may formed using a second manufacturing process. The second manufacturing process may comprise an additive manufacturing technique.

A hybrid torque tube for a brake assembly may comprise a tube portion having a centerline axis, and a conical back-leg portion extending from the tube portion. A stator spline may be formed on a radially outward surface of the tube portion. A foot may be formed on a radially inward surface of the tube portion. The tube portion is formed using a first manufacturing process and at least one of the conical back-leg, stator spline, or foot is formed using additive manufacturing.

The disclosed invention relates to an article, comprising: a substrate having a surface comprising aluminum or an aluminum alloy; a sealed anodic coating layer overlying at least part of the surface of the substrate; and a layer of a silicon-containing polymer overlying the sealed anodic coating layer. The article may be useful as a brake or wheel component.

Treated aluminum article and method for making same

Disclosed is a chromium-nickel stainless steel alloy article having an adherent, wear resistant coating of metallic oxides and a method of forming an adherent, wear resistant coating of metallic oxides on a chromium-nickel stainless steel alloy article. The coating desirably has a thickness of from about 25.4 to about 102 microns (1 mil to about 4 mils) and is formed by exposure of the article to an oxidizing atmosphere, preferably air, preferably during heat treatment of the article. Such articles are useful, inter alia, as torque drive inserts for a friction disk for a multi-disk brake or clutch assembly. The drive inserts can be formed of an alloy such as 17-4PH stainless steel alloy having an adherent coating of lubricious oxides formed during frictional contact. It is believed that these lubricious oxides will form also if the heat treated base alloy is subject to temperatures greater than 815.6&#xb0; C. (1500&#xb0; F.) for a sufficient time in an oxidizing atmosphere.
