A torque bar manufactured by an additive manufacturing process is provided. The torque bar may include a torque bar body made of more than one metallic material. The torque bar may also include a geometry that comprises one or more voids and one or more webs, as well as a varied geometry in the direction of a longitudinal axis. The torque bars can exhibit characteristics, such as vibration damping, tuned stiffness, and tuned bending resistance in order to enhance dynamic stability.

Torque bar and methods for making

A method for creating a metallurgic component comprises creating a thin-walled container corresponding to a shape of the metallurgic component from a metal. If powder metal is not already in the container (depending on a method of creating the container), the thin-walled container is filled with powder metal. A quick-can device is fixed to the thin-walled container, and the powder metal is consolidated inside the thin-walled container (e.g., in a hot isostatic press). During consolidation, pressure within the thin-walled container is monitored and a desired pressure differential between an inside of the thin-walled container and an outside of the thin-walled container is maintained by the quick-can device.

Using thin-walled containers in powder metallurgy

According to various embodiments, disclosed is an axle saddle system for an axle having an undercut between the outboard and inboard bearing lands of the axle. According to various embodiments, the axle saddle system comprises a saddle configured to fill the axle undercut in order to protect the axle from damage by the installation of a wheel onto the axle.

Systems and methods for brake cable adjustment are disclosed herein. In this regard, a gage block tool for adjusting a brake cable may comprise a body comprising, a first member extending in a first direction, the first member having a first length and a first thickness, and a second member extending in a second direction, the second member having a second length and a second thickness. At least one of the first member or the second member may be sized and configured to be placed between a stop and a lever of a brake valve, the brake cable connected between the lever and a brake handle being properly adjusted when the gage block sandwiched between the lever and the stop contacts both the lever and the stop while the brake handle is in a park lock position.

A method includes measuring a brake temperature of an aircraft brake using a sensor; determining a brake heat sink mass of the aircraft brake using a wear measuring device; and calculating a turnaround threshold based upon the measured brake temperature and the determined brake heat sink mass.

System and method for determining an adaptive turnaround threshold

A wheel assembly () is disclosed, including a wheel base () and a wheel rim member (). The wheel base () has along at least a portion of its length a non-circular cross sectional outer surface (). The wheel rim member () has along at least a portion of its length a mating non-circular cross sectional inner surface (). The inner surface () of the wheel rim member () interacts with the outer surface () of the wheel base () to restrict relative rotation of the wheel rim member () on the wheel base ().

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.

Disclosed is a ferrous metal article having a protective, adherent, wear resistant coating of metallic oxides and a method of forming a protective, adherent, wear resistant coating of metallic oxides on an iron-chrome article. The coating desirably has a thickness of from about 12.7 to about 102 microns (&frac12; 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.
