| titleOfInvention | Manufacture of hollow extrusion material to be formed for vacuum made of a1 or a1 alloy |
| abstract | PURPOSE: To obtain the hollow extrusion material to be formed made of Al or Al alloy for the vacuum to make the super high vacuum state in a short time by bringing the cooling gas to flow along the hollow inside surface of the hollow extrusion material to be formed made of Al or Al alloy and forcedly cooling the inside. n CONSTITUTION: At the same time of the extrusion after entering the bullet 8 of Al alloy in the container 7, the cooling gas is brought to flow in the hollowed part of the extrusion material to be formed 1 from the gas injecting nozzle 13. As the cooling gas, the liquid nitrogen in the liquid nitrogen tank 19 is evaporated with the evaporation vessel 18 and the nitrogen gas is brought to flow. Therefore, the amorphous oxidized film is formed on the inside surface of the extrusion material to be formed 1, the hollow extrusion material to be formed made of Al for vacuum which can attain the super high vacuum state in a short time is obtained. n COPYRIGHT: (C)1991,JPO&Japio |
