A process chambercomprising a container (), a lid (), and a sealed interface () therebetween. The container's interface surface () and/or the lid's interface surface () includes at least one groove () in which a seal () is situated. The seal () comprises an elastomeric element () and a metallic element (). The elastomeric element () and the metallic element () can be arranged and adapted to seal the chamber's interface () sequentially during its conversion to a sealed condition. And/or the elastomeric element () and the metallic element () can be arranged and adapted to seal the chamber's interface in series once the lid () is in its sealed condition.

Semiconductor process chamber

A seal () includes a first component () and second component (), the first component including a first material having a high thermal and oxidation and wear resistance, and the second component () including a second material that is different from the first material and has a high spring load maintenance. The seal () is applied to a combustion chamber for a gas turbine, where the first component () extends between the casing wall of the combustion chamber and adjacent liner segments (). The spring load of the second component () provides a seal also in the case of vibrations in a combustion chamber. The lifetime of the seal () is increased due to the individual materials, which are optimally chosen for the functions of high thermal and wear resistance and spring load maintenance respectively. The seal is further applied to the sealing between adjacent stationary blade platforms in gas turbines.

High temperature seal and methods of use

It is disclosed a seal assembly () which comprises a layered structure. It consists of a first layer () of a base material, a second layer () of thermal insulating material on top of the base material and a third layer () of base material or an oxide resistant material on top of the second layer () of thermal insulation. The inventive seal assembly () described herein can be arranged between combustor liner segments ().

Seal assembly

A metallic seal includes a cold formed substrate layer and one or more additional layers. At least one of the layers offers improved resistance to high temperature stress relaxation.

High temperature metallic seal

A seal has a metallic body having a convoluted cross-section extending between first and second ends and a first generally interior surface extending between the first and second ends and a second generally exterior surface extending between the first and second ends. An adhesive is located in one or more locations on at least one of the surfaces, the adhesive holding the body in a longitudinally contracted condition. There are related methods of manufacture. In related methods of use, the adhesive is caused to release, allowing the seal to expand toward the relaxed condition.
