Cathodic protection using thermal spray of supporting columns and monopiles is available to prevent severe corrosion of these components immersed in sea water. Various components currently made from stainless steel are being substituted with high nickel chrome alloys applied by thermal spray as they are particularly resilient to sea water corrosion and adverse wear. 

The Castolin Eutectic workshop in Newcastle has developed a series of composite coatings to combat the aggressive environments associated with biomass incinerators. High chloride, ash build up, high temperature oxidation and solid particle erosion effects have all been successfully abated. 

The Castolin Eutectic workshop in Newcastle currently has a series of coatings which combat problems of corrosion and wear on components such as Nacelle Housing, supports, cast iron hubs. Cathodic protection of the main shaft, tower and foundations, wear protection in the gearbox and various established technologies associated with the generators are available.
