  • Patent number: 9957590
    Abstract: A new pre-alloyed metal based powder, intended to be used in surface coating of metal parts. The powder is deposited using e.g. laser cladding or plasma transfer arc welding (PTA), or thermal spray (e.g. HVOF). The powder is useful for reducing friction and improving wear reducing properties of the deposited coating. Such coatings may also improve machinability. As friction or wear reducing component, inclusions of manganese sulphide or tungsten sulphide in the pre-alloyed powder may be used.

  • Publication number: 20180066343
    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.
