Protection of steel exposed to high temperature areas, in particular those which are insulated, provides some of the most demanding situations faced by coatings. Systems applied in these areas are required not only to give resistance to high operating temperatures (which are often cyclic) but also provide corrosion protection.

This paper provides an outline of the development work undertaken and performance advances made with new generation “cold spray aluminium” technology in comparison to traditional high temperature coating systems. An introduction into developed test methodologies for coating evaluation (both insulated and atmospheric service), as well as product performance both laboratory and field based, is also described.
