The problems of corrosion at elevated temperatures are met with a new inorganic aluminum ceramic coating known as Sermetel. This is a water based special coating in which the aluminum pigmentation is stable in the aqueous phase and a corrosion protection effect maintained. Continuous development of this material may well, one day, enable the expensive cupro nickel chrome alloys to be used less and perhaps even large steel structures may be internally protected with the thermally cured aluminum ceramic coating. This type of coating does have its limitations however, especially where the environment is highly acidic or alkaline. In these cases a coating of PTFE suitable for service at temperatures around 250 degree C has been developed. This material is characterized by its high resistance to chemical attack and the lowest coefficient of friction of all material so far developed.
