Corrosion Resistant Coatings


Acree Technologies offers a series of corrosion resistant coatings. These coatings are used in applications ranging from salt water exposure in marine environments, to the inside of oil pipelines, to coatings for pacemaker electrodes for heart patients. Frequently, these applications also require wear or erosion resistance. For example, propellers on small, shallow water craft require corrosion resistance against sea water but also resistance to erosion from sand and cavitation effects. At ATI we have developed coating systems that satisfy this dual role - increased corrosion resistance while providing increased mechanical durability. An example of corrosion testing is shown in the figure below. Both parts were submerged in a customer specified salt water brine mixture for an extended period of time. The uncoated part shows significant corrosion damage, typical of the customers experience with uncoated components. In contrast, the coated part shows no corrosion damage following the same exposure. Acree works with our customers to develop specific solutions for their corrosion problems.
