Galvanic Corrosion Between Aluminum and Graphite
We are in need of an anti-corrosion product that has a very thin film and will not reduce the thermal conductivity properties of the material it is adhered to. We manufacture aluminum castingÝ(direct chill) equipment that has a graphite liner and is backed by a water cooled aluminum mold. The corrosion is taking place between the graphite and aluminum surfaces which is a low pressure intermittent contact area. The molten aluminum (700 degrees C) is in contact with the graphite liner which is in turn cooled by the water cooled aluminum mold. The heat transfer between the graphite and the aluminum is critical to our process. We are looking for a solution to our corrosion problems. Any suggestions?
