DURCH EIN THERMISCHES AUFTRAGSVERFAHREN HERGESTELLTE SCHUTZSCHICHT UND PULVERFOERMIGE WERKSTOFFE ZUM HERSTELLEN DERSELBEN.

摘要

The protection layer is comprised of an alloy having the following composition: C 0.5-1.5 ; Si 0.5-4.5 ; Mn 0.1-1.5 ; Cr 14-30 ; Mo 0.1-17 ; Fe 0.1-5 ; B 0.1-3.8 ; Co 0.01-1 ; W 0.2-5 ; Ni the rest. The pulverulent material for the preparation of the protection layer is comprised of a mixture of alloys A, B and C in the ratio 20 - 50 / 20 - 50 / 25 - 45% by weight, distributed as follows: A : 20%-50% ; B : 20%-50% ; C : 25%-45%. The layer obtained is thermostable up to 600<o>C and has a good resistance to wear and corrosion.
