Abstract: The invention relates to a method for hot-dip coating a metal bar (1), particularly a steel strip, according to which at least some sections of the metal bar (1) are vertically directed through a container (3) receiving the molten coating metal (2) at a given conveying speed (v). In order to influence the quality of the coating process, the time (t) during which the metal bar (1) remains in the molten coating metal (2) is predefined by controlling or regulating the surface level (h) of the molten coating metal (2) in the container (3). The invention also relates to a device for hot-dip coating a metal bar.

Abstract: Substrate such as a turbine blade provided with a coating, which consists of a material that forms a sealing oxide skin on heating. This material is a ferrous metal aluminium alloy or a ferrous metal chromium alloy, wherein the oxide skin comprises aluminium oxide or chromium oxide, hi order to optimise the adhesion between the skin and the coating, it is proposed that a metal from the platinum group such as platinum or palladium be added in an amount of 0.1 - 0.5 % (m/m). It has been found that better adhesion is obtained with this method and the detrimental effects of sodium, potassium or calcium are counteracted.

Abstract: Nach dem Stand der Technik ist es sehr aufwändig die Schichtdicke während eines Beschichtungsverfahrens zu bestimmen. Dabei müssen Referenzproben geschnitten und damit zerstört werden, um eine Schichtdicke zu kontrollieren. Nur wenn die Referenzprobe die gewünschte Schichtdicke aufweist, können die Bauteile verwendet werden, die zusammen mit der Referenzprobe beschichtet wurden.
Ein erfindungsgemäßes Verfahren zur Schichtdickenbestimmung, erlaubt es, die Schichtdicke während des Beschichtungsverfahrens in-situ zu bestimmen, wobei ein Sensor verwendet wird, der durch das Beschichtungsverfahren in repräsentativer Weise zur jeweils erreichten Schichtdicke eine elektrische Eigenschaft verändert, die gemessen wird.
