Support for the detection of corrosion sensitive metal surfaces and method for the detection of corrosion sensitive metal surfaces

摘要

Support for the detection of corrosion of metal surfaces or of corrosion sensitive metal surfaces, in particular of surfaces of stainless steel, comprising a base body (21) of the chloride or bromide and potassium hexacyanoferrate in dissolved form, wherein the base body (21) is largely transparent and on the basis of a polymer, polymer mixture is formed or of a gel.
