Abstract: A laser cladding or plasma transferred arc overlay welding process may be used advantageously to apply and to control the material properties of a coating designed for protecting the substrate against wear, corrosion and oxidation at elevated temperature. Furthermore, a laser cladding or plasma transferred arc overlay welding process may be used to apply the coating alloy materials in applications where traditional thermal spray or weld-applied coatings are not practical. By using these welding methods very good bonding is achieved by fusion during welding. At the same time the properties of the clad layer is preserved by the limited dilution typical of these two welding methods compared traditional overlay welding, by e.g. Gas Tungsten Arc Welding and the like.
