METHOD FOR MAKING STEEL OR TITANIUM PRODUCTS CONTAINING A PRECIPITATION-HARDENING NICKEL-BASE ALLOY, AND PART

摘要

Combining a precipitation-hardening nickel-base alloy with a steel or titanium substrate makes it very easy to repair parts, the nickel-base alloy having good erosion-resistant properties. A method for producing is disclosed. In particular for repairing, a component having a substrate, in particular turbine blades made of steel or titanium, in particular made of martensitic or precipitation-hardening chromium-rich steels, with a localized deposition weld or with an affixed shaped part, in which a precipitation-hardening nickel-based alloy is used as the localized deposition weld or as the shaped part, in which a laser powder deposition weld or an arc deposition weld is performed.
