Laser clad layer Quarite NR+
Quarite NR and Quarite NR+ have the highest corrosion resistance of the Topclad laser clad layer portfolio. This is due to the high percentage of molybdenum in this nickel-based superalloy. These two layers only differ in hardness and wear resistance. Quarite NR+ provides the best protection in extreme high corrosive conditions with moderate to high wear.
