Beschreibung
Zusammenfassung:	A thermal spray material feedstock is provided that includes an iron-based alloy having 5-12 wt% of Al; 1.8-7.5 wt% of B; 0-2 wt% of C; 0-4.5 wt% of Mo; 0-6.5 wt% of V; and a balance of Fe. The iron-based alloy is substantially free of chromium and nickel. L'invention concerne une charge de matériau de pulvérisation thermique qui comprend un alliage à base de fer ayant 5 à 12 % en poids d'Al; 1,8 à 7,5 % en poids de B ; 0 à 2 % en poids de C ; 0 à 4,5 % en poids de Mo ; 0 à 6,5 % en poids de V ; et le reste de Fe. L'alliage à base de fer est sensiblement exempt de chrome et de nickel.
