Beschreibung
Zusammenfassung:	A coated edge welded metal bellows is provided. The coated edge welded metal bellows is generally formed by welding a plurality of convoluted diaphragms together. The coating is deposited using a chemical vapor deposition process such that both sides of the connected diaphragms are coated by a continuous surface coating that also encompasses the welds. The coating is an organic coating, such as, for example, poly para xylylene. L'invention concerne un soufflet métallique soudé à bord revêtu. Le soufflet métallique soudé à bord revêtu est généralement formé par soudage d'une pluralité de diaphragmes convolutés les uns aux autres. Le revêtement est déposé à l'aide d'un procédé de dépôt chimique en phase vapeur de telle sorte que les deux côtés des diaphragmes connectés sont revêtus par un revêtement de surface continue qui englobe également les soudures. Le revêtement est un revêtement organique, tel que, par exemple, le polyparaxylylène.
