BFSV research into corrosion control
Corrosion is a risk factor in the transportation of goods. In their travels around the world, containers frequently pass through several climatic zones. Fluctuations in temperature give rise to condensation. Every year, businesses suffer losses on a substantial scale as a result of rust forming on their metal products.
Two methods of preventing such corrosion during storage and transport have proved successful:
- a desiccant is used to take up and bind the water (desiccant method)
- molecules of a volatile corrosion inhibitor are deposited on the surface of the metal to inhibit the corrosion processes (VCI method)
At the BFSV Institute we have developed a computer-controlled test stand. This can put specimens of sheet metal through up to 15 different dew cycles. In the interests of realistic testing, these plates may be also bear traces of deep-drawing lubricants or welding spots. For targeted tests, we can also run the test stand in a climate chamber. This makes it possible to adapt the ambient conditions to a specific shipment method or route. This research work delivers made-to-measure results for VCI applications. In this way BFSV’s research work provides the basis for targeted, reliable and cost-effective use of corrosion control products in practice.
