Abstract
Solid metal introduced into a molten metal to modify it is protected against oxidation at elevated temps. by a coating of another metal resistant to oxidation and compatible with the molten metal. The method is esp. suitable for de-oxidation of molten Cu or its alloys with a lanthanide (esp. mischmetal) bar or wire coated with Cu or its alloys.
