| titleOfInvention | Tube having regions of different surface chemistry and method therefor |
| abstract | In a method to modify the chemistry of a portion of the surface of an article, the surface is placed adjacent an electrode in a plasma chamber, the distance to the wall of the chamber being at least five times the size of the electrode. A plasma of very high power density is generated in a discharge volume surrounding the electrode so that the surface area closest to the electrode receives a very intense plasma which, diminishes with increasing distance from the discharge volume thus forming a chemical gradient on the article surface. The preferred article is a tube having one closed end, and the gradient may be formed from either the closed end or the open end. The gradient may be of decreasing glass-like character or decreasing plastic-like character. |
