Corrosion-resistant iron-base material and a process for producing same

摘要

A corrosion-resistant iron-base material coated on at least a part of the surface thereof with a layer of a titanium-nickel alloy containing 5-45% by weight of nickel. This corrosion-resistant iron-base material is produced by applying a viscous coating liquid containing titanium powder, nickel powder and a binder onto the surface of an iron-base alloy and then heating the iron-base alloy at a temperature of 900 DEG -1200 DEG C. under vacuum so as to form on the surface thereof a layer of the titanium-nickel alloy containing 5-45% by weight of nickel.
