Abstract

Cobalt-based solder alloys are proposed. The cobalt-based solder alloys have germanium. The germanium has a higher melting point than nickel-based alloys such that the germanium is used advantageously for repairing or treating components having the nickel-based alloys used at high temperatures. The components are repaired or treated by soldering using the cobalt-based solder alloys.
