The importance of corrosion on the erosion-corrosion performance of thermal spray ceramic-metallic coatings

This paper reviews some data regarding the combined effect of erosion and corrosion of thermal spray ceramic-metallic coatings and their potential application in sea water and production systems for the oil industry. The paper also presents recent research results from SINTEF Corrosion and Surface Technology with respect to development of new and better ceramic-metallic coatings from the Norwegian coating industry. It has been shown that taking new high velocity spraying technology into use in combination with recent developed powders, the result is a more corrosion and erosion resistant coating than the traditional and most often specified type Praxair LW45.
