Practical demonstration of the efficacy of volatile corrosion inhibitors using plane specimens - BFSV test method

摘要

In the sphere of temporary corrosion control for semifinished metal products the VCI (Volatile Corrosion Inhibitor) method has established itself successfully on the market. In the past the efficacy of the VCIs has been demonstrated in laboratory tests (delivery standards) which take little account of exposure under practical working conditions. The reproducibility of the results is also limited. In the context of AIF project 12115 (supported financially by the Federal Ministry of Economics) the BFSV Institute at Hamburg University of Applied Sciences has developed and verified a test method that correlates strongly with metal surfaces under practical conditions and produces results with good reproducibility. Procedures for determining actual climatic load profiles and an objective method of assessing the degree of corrosion have also been elaborated.
