Abstract
A method for making a container for retaining anesthetic agent. The method includes creating two or more parts each having a mating surface, where the container is formed when the mating surfaces of the two or more parts are coupled together, and where a first part of the two or more parts is formed of a material having pores defined within the mating surface thereof. The method further includes processing the mating surface of the first part via friction stir welding to reduce the pores defined therein. The method further includes coupling the two or more parts together such that the mating surfaces contact to create the container configured to retain the anesthetic agent therein.
Claims14
A method for making a container for retaining anesthetic agent, the method comprising:
- creating two or more parts each having a mating surface, wherein the container is formed when the mating surfaces of the two or more parts are coupled together, and wherein a first part of the two or more parts is formed of a material having pores defined within the mating surface thereof;
- processing the mating surface of the first part by performing visco-plastic stirring with a friction stir welder to reduce the pores defined therein;
- and
- coupling the two or more parts together such that the mating surfaces contact to create the container configured to retain the anesthetic agent therein.
A method for making a container for retaining a gas or liquid, the method comprising:
- casting a first part of a metallic material, wherein the first part has a first mating surface and a non-mating surface, and wherein the metallic material has pores defined within the first mating surface;
- processing the first mating surface of the first part by performing visco-plastic stirring with a friction stir welder to reduce the pores defined therein;
- obtaining a second part made of a metallic material, the second part having a second mating surface and a second non-mating surface, wherein at least one of the first part and the second part defines a passageway;
- and
- brazing the first part and the second part together such that the first mating surface of the first part is in contact with the second mating surface of the second part;
- wherein a reservoir is formed between the first non-mating surface of the first part and the second non-mating surface of the second part when the first part and the second part are brazed together, wherein the reservoir is configured to retain the gas or liquid therein, and wherein the container is configured such that the gas or liquid exits the reservoir only via the passageway.
