Coatings research carried out by The Welding Institute (TWI) and the University of Cambridge could lead to improved high-temperature oxidation and corrosion protection for engineering components.

The work, on high-velocity oxy-fuel thermal spraying, is being carried out by James Hearley under the TWI/University of Cambridge postgraduate training partnership. The aim is to use the process to solve problems in gas turbine and waste incineration plants, by applying a low porosity, strong adherent coating of nickel-aluminide to components.

TWI said initial results show the coating provides improved properties compared with nickel alloys and stainless steel the conventional materials.
