Composite laser claddings for corrosion protection of outer surfaces of storage containers for spent nuclear fuel in underground repositories

Popis výsledku v původním jazyce

The present contribution examines the structures of and corrosion processes in copper-basalt compo-site laser claddings on a steel substrate. The cladding material was a laboratory-prepared mixture of the following components: Oerlikon METCO 55 (Cu > 99.9 %) and basalt powder. The metallo-graphic structures of copper-basalt composite laser claddings were studied using optical and scanning electron microscopy. The adhesion of the claddings to the substrate was testing using the non-standardized Mercedes test. A potentiodynamic corrosion test in artificial mine water was performed on a specimen of the composite laser cladding. The test results were compared against those for a reference high-purity copper alloy C10100 and AISI 304 steel. The findings were interpreted in terms of the potential of copper-basalt composite laser claddings to be used as corrosion protection coat-ings on steel components in nuclear power applications.
