ZVO corrosion test with Metrohm-Minilab

Hoveddokument


Previously, time-consuming corrosion tests in the form of salt spray tests were carried out for the purpose of process monitoring of conversion layers and seals on zinc and/or zinc alloys. The working group of the Central Association for Surface Technology (Zentralverband Oberflächentechnik e.V. (ZVO)) has developed a test that can provide the coating appliers with information regarding the quality of the coating more quickly. This article shows how Deutsche Metrohm Prozessanalytik is implementing the ZVO testing method with the Minilab system.
