摘要:
An article having a sealed layered edge, e.g. an automotive laminate and a multiple glazed unit includes a pair of glass sheet in a fixed relationship with one another. A sputtered coating is deposited on a major surface of one of the sheets and includes at least one combination of a metal film, e.g. a silver film and a dielectric film. Discontinuities in the metal film at the marginal edges of the coated sheet provide voids in the metal film to impede or stop corrosion of the metal film. The discontinuities include (1) break lines or segments in the coating, (2) coating thickness variations provided by abrading the coating and (3) spaced discrete coating areas on the marginal edges of the coated sheet. The discontinuities may be made in the metal film using a laser, an abrasive surface, a coating mask and/or coating deletion techniques.
摘要(中):
具有密封层状边缘的物品,例如汽车层压板和多层玻璃单元包括一对彼此固定关系的玻璃板。 溅射涂层沉积在其中一个薄板的主表面上,并且包括至少一种金属薄膜,例如银薄膜和电介质薄膜的组合。 金属膜边缘的金属膜中的不连续处在金属膜中提供空隙以阻止或阻止金属膜的腐蚀。 不连续性包括(1)涂层中的断裂线或片段,(2)通过研磨涂层而提供的涂层厚度变化,以及(3)涂覆片材的边缘边缘上的间隔开的不连续涂层区域。 可以使用激光,研磨表面,涂层掩模和/或涂层删除技术在金属膜中制造不连续性。 p>
