Abstract

A wire-form spray material, in particular for arc wire spraying, essentially comprising iron. The spray material is formed at least with carbon as a microalloy such that upon solidification of the spray material a fine pearlitic, bainitic, martensitic structure arises in which finely dispersed nitrides are present.
