METHOD OF MATERIALS HARDENING Russian patent published in 2005 - IPC

Abstract RU 2252971 C1

FIELD: mechanical engineering; aircraft industry; ship building.

SUBSTANCE: the invention is dealt with the fields of plastic metalworking and may be used in aircraft industry, shipbuilding industry, engineering industry. The substance of the invention consists in expansion by an internal pressure of a compression working thin-wall cylindrical rack up to the necessary collected deformation ensuring an increase of a conventional yield point of squeeze. The offered method will increase strength of compressed of thin-wall elements of designs and so to increase reliability of machines and gears.

EFFECT: the invention ensures increased strength of compressed of thin-wall elements of designs and so to increase reliability of machines and gears.
