anodizing

Aviation; Aeronautics

A method of preventing corrosion of aluminum alloy parts. A hard oxide film is formed on the surface of the metal by an electrolytic process. This film prevents oxygen reaching the surface of the ...

A method of producing a close fit between two metal parts by rubbing them together with a very fine abrasive lapping compound between them. The fit of a lapped joint is checked by removing all the ...

mass production

Aviation; Aeronautics

A method of producing large numbers of identical objects by the use of specialized jigs and fixtures. In the process of mass production, the manufacturing procedure is broken down into small steps ...

jet propulsion

Aviation; Aeronautics

A method of propulsion by thrust produced as a relatively small mass of air is accelerated through a large change in velocity.

cladding

Aviation; Aeronautics

A method of protecting aluminum alloys from corrosion by rolling a coating of pure aluminum onto the surface of the alloy. Cladding is done in the rolling mill.

passivation

Aviation; Aeronautics
