A process in the heat treatment of steel in which some of its hardness and brittleness are removed. The steel is first hardened by heating it to the correct temperature and then quenching it in oil, water, or brine. This makes the steel hard, but also brittle. The hard steel is then reheated, but to a lower temperature, and held at this temperature for a specified period of time. It is then allowed to cool to room temperature in still air. This reheating and cooling is called tempering.
Industry:Aviation
A process in the manufacture of sensitive electronic equipment in which the equipment is operated for a specified period of time. The burning-in period shows up weak or faulty components, and stabilizes the operating characteristics of the components.
Industry:Aviation
An instruction issued to a pilot on an instrument approach, directing him to continue inbound to the missed-approach point and then to execute the missed-approach procedure, as described on the Instrument Approach Procedure Chart or as previously assigned by ATC.
Industry:Aviation
A process in which a chemical is used to microscopically roughen the surface of a metal. Chemical etching is used to prepare a metal so primer will form a tight bond to its surface.
Industry:Aviation
A process in which molten metal is deposited on a surface. A wire of the metal to be deposited is fed into an oxy-acetylene flame and melted. The molten metal is blown by a stream of high-pressure air onto the surface to be coated.
Pure aluminum can be sprayed onto steel to prevent corrosion, and metal can be sprayed onto an insulating material to make the surface electrically conductive.
Industry:Aviation
A process in which part of the energy in the output of an electronic circuit is fed back to the input through a capacitor.
Industry:Aviation
A process in which powdered metal is heated but not quite melted and then squeezed together.
Industry:Aviation
A process in which various manufacturing steps are programmed so they can be performed automatically, without requiring any input from a human operator.
Industry:Aviation
A process of preparing holes in sheet metal to receive flush rivets.
The metal in the area to be dimpled is heated, and a coining die is pressed into it. The pressure of the die in the softened metal gives the dimpled hole sharp edges that provide a good fit for the countersunk rivet heads.
Industry:Aviation
A process of strain-relieving steel that has been machined, welded, or worked in any way that leaves it in a strained condition. The steel is heated to a specified temperature, usually red-hot, and then allowed to cool in still air to room temperature.
