(Main)Aerospace series - Vacuum deposition of cadmium
Aerospace series - Vacuum deposition of cadmium
This document specifies the method for depositing cadmium layers according to the vacuum deposition
process, for use in aerospace construction.
According to this process, cadmium metal is vaporized under vacuum and deposited directly on the
base material with an interlayer. The coating produced in this way is ductile and electrically conductive.
This document is applicable whenever referenced.
Luft- und Raumfahrt - Aufdampfen von Kadmium im Vakuum
Dieses Dokument legt das Verfahren zum Aufdampfen von Cadmiumschichten durch Vakuum-Aufdampfverfahren zur Verwendung bei Konstruktionen in Luft und Raumfahrt fest.
Nach diesem Verfahren wird im Vakuum Cadmiummetall verdampft und mit einer Zwischenschicht direkt auf dem Grundwerkstoff niedergeschlagen. Die so erzeugte Schicht ist duktil und elektrisch leitend.
Dieses Dokument ist immer dann anzuwenden, wenn darauf verwiesen wird.
Série aérospatiale - Cadmiage sous vide
Le présent document spécifie la méthode pour déposer des couches de cadmium selon le procédé de cadmiage sous vide, pour utilisation dans la construction aéronautique.
Selon ce procédé, le métal cadmié est vaporisé sous vide et déposé directement sur le matériau de base avec une couche intermédiaire. Le revêtement produit de cette manière est ductile et électroconducteur.
Le présent document est applicable chaque fois qu’il est cité en référence.
Aeronavtika - Usedline kadmija v vakuumu
Ta dokument določa metodo za odlaganje plasti kadmija v skladu s postopkom vakuumskega odlaganja za uporabo v aeronavtiki. V skladu s tem postopkom se kadmij upari pod vakuumom in odloži neposredno na osnovni material z vmesno plastjo. Tako izdelana prevleka je duktilna in električno prevodna. Ta dokument se uporablja vedno, kadar se nanj sklicuje.
