In this article, the authors study how galvanodiffusive saturation with lanthanum or neodymium influences the high-temperature oxidation resistance of nickel and nichrome. A convenient electrolyte was used which contained chlorides of the rare earth and barium and fluorides of potassium and calcium. Results show that surface alloying with rare-earth metals is more promising than bulk alloying, since it can reduce the metal consumption of structures and components of scarce nickel alloys and can increase the effective working temperature.
