Abstract
A material in powder or wire form on a nickel basis for the production of a coating with a high level of resistance to corrosion and wear by means of a thermal coating process is of the following composition (in percent by weight): C 0.005-1.0; Cr 10.0-26.0; Mo 8.0-20.0; Fe 0.1-10.0; Si 3.0-7.0; B 1.0-4.0; Cu 0.1-5.0; Ni Balance. The material in powder form can be alloyed and sprayed out of the melt or agglomerated out of different alloyed and non-alloyed metal powders. The coating material can also be used in the form of a filling wire or an alloyed and cast bar material.
