A method for the treatment of a substrate to provide protection against corrosion and apparatus for degassing of the process medium used in this case liquid

摘要

A method for the treatment of a substrate for the purpose of corrosion protection, in which the substrate in a dipping bath containing a process medium is treated, wherein said for the treatment process medium provided in the immersion bath before, during and / or after the treatment is degassed, characterized in that the process medium in the course of the supply to a degassing container (10) in this is above a liquid level (15) of the process medium in the degassing container (10) the degassing container (10) and fed via a spreading arrangement is distributed, so that the process medium flows through this, before the process medium into a lower region of the degassing container (10) passes.
