High Performance Ceramic Coatings
ACI 3200 is a coating composition formulated for protecting ferrous alloys from both high heat temperature heat oxidation and at the same time offer sacrificial (cathodic) protection to the base metal.
Because of its high temperature capabilities, it offers excellent protection when exposed to cyclic high temperature and corrosive salt environments, continuing to provide sacrificial properties at temperatures to 1150 degrees Fahrenheit. Although a ceramic coating, it combines thermal stability, excellent adhesion and hardness, along with good flexibility, a property not found in most ceramic coatings. As mentioned above it offers salt corrosion protection to 1150 degrees Fahrenheit. At about 1200 degrees Fahrenheit the aluminum oxidizes to a point where it no longer provides its excellent sacrificial properties, however it will continue to offer excellent heat oxidation continuously to 1600 degrees Fahrenheit and in some cases depending on metal substrate, has offered heat oxidation protection to 2200 degrees Fahrenheit.
Further, the coating formed from ACI 3200 composition offers superb thermal shock resistance. The coated metal will not crack, spall or fail after shocking from 1100 degrees Fahrenheit to room temperature repeatedly.
