Abstract
An article is provided manufactured by an ion-beam-assisted-deposition process. The article includes a polymeric element adapted to releasably engage a contact surface. The polymeric element is provided with a surface layer bonded to a surface of the polymeric element through an ion-beam-assisted-deposition process in order to reduce the tackiness of the polymeric material.
Claims22
An article of manufacture including a plunger having an engagement surface formed of a polymeric material for releasably engaging a contact surface extending around an aperture whereby fluid flow through the aperture is controlled, the improvement comprising:
- a surface layer defined on said engagement surface to reduce a force resisting separation of said engagement surface from said contact surface, and
- wherein said surface layer is formed on and bonded to said engagement surface by an ion-beam-assisted-deposition process.
An article produced through an ion-beam-assisted-deposition process comprising:
- a rigid body;
- a polymeric element supported on said rigid body such that said rigid body and said polymeric element define a plunger for moving into engagement with a valve seat, and
- wherein said polymeric element includes an engagement surface, and including a surface layer formed on and bonded to said engagement surface through said ion-beam-assisted deposition process.
An article of manufacture including a valve seat having an aperture extending therethrough, said valve seat defining a contact surface formed of a polymeric material, said contact surface being adapted to releasably engage an engagement surface on a plunger whereby fluid flow through the aperture is controlled, the improvement comprising:
- a surface layer defined on said contact surface to reduce a force resisting separation of said engagement surface from said contact surface, and
- wherein said surface layer is formed on and bonded to said contact surface by an ion-beam-assisted-deposition process.
