  • the preparation by blasting and the spraying process were carried out in the spraying workshop using a mechanical movement device for the spray gun and workpiece.
  • the superheater tubes were welded together and installed in the boiler.
  • the coated surface of the treated pipes was checked for corrosion attack and the layer thickness of the coating. There was only a very small, flat attack on it. From the values found, it can be deduced that the service life of the pipes has been extended by about three times before they are replaced.
  • the autogenous flame spraying process was chosen to create the coatings in situ, and the following composition (in% by weight) as powdered spraying material:
  • the grain size range was between 37/105 ⁇ m, the suggested layer thickness between 0.5 and 0.6 mm.
