Aerospace series - Vacuum deposition of cadmium

This standard defines the method for depositing cadmium layers according to the vacuum deposition process, for use in aerospace construction.
According to this process, cadmium metal is vaporised under vacuum and deposited directly on the base material with an interlayer. The coating produced in this way is ductile and electrically conductive.
This standard is applicable whenever referenced.

Luft- und Raumfahrt - Aufdampfen von Kadmium im Vakuum

Diese Europäische Norm legt das Verfahren zum Aufdampfen von Kadmiumschichten durch Vakuum-Aufdampfverfahren zur Verwendung bei Konstruktionen in Luft- und Raumfahrt fest.
Nach diesem Verfahren wird im Vakuum Kadmiummetall verdampft und mit einer Zwischenschicht direkt auf dem Grundwerkstoff niedergeschlagen. Die so erzeugte Schicht ist duktil und elektrisch leitend.
Diese Norm ist immer dann anzuwenden, wenn auf sie verwiesen wird.

Série aérospatiale - Cadmiage sous vide

Cette Norme européenne définit la méthode pour déposer des couches de cadmium selon le procédé de cadmiage sous vide, pour utilisation dans les constructions aéronautiques.
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 électriquement conducteur.
La présente norme est applicable chaque fois qu’elle est citée en référence.

Aeronavtika - Usedline kadmija v vakuumu

Ta evropski standard opredeljuje metodo za odlaganje plasti kadmija v skladu s postopkom usedlin v vakuumu, za uporabo v aeronavtični gradnji. V skladu s tem postopkom, se kadmijeva kovina upari v vakuumu in odlaga neposredno na osnovni material z vmesnim slojem. Premaz, ki se proizvaja tako, je duktilen in električno prevoden. Ta standard se uporablja, kadar je naveden.
