Description
In this study, rotating experimental devices were built to investigate the compatibility of the fusion reactor materials RAFM steel, 316L(N) steel，CuCrZr alloy with the Al2O3–water nanofluids. Based on the ITER water-cooling program，the experimental condition parameters were fluid velocity of 1.13 and 3.71m/s，fluid temperature of 70±1◦◦C，testing duration of 2136h，nanofluid mass fraction of 0.01 wt.%，1 wt.%，etc. The observation and analysis in compositions by SEM,EDS,XPS for the specimen surfaces were performed．The preliminary results indicate that the compatibility of RAFM steel and 316L(N) steel with nanofluids is better than that of CuCrZr alloy.The surface of CuCrZr alloy is covered by oxide film with holes and cracks. Furthermore, the surface morphology of CuCrZr alloy in nanofluids is strongly dependent on the testing duration, flowing velocity and mass fraction. The corrosion mechanism is dominated by oxygen absorption corrosion and erosive-corrosive wear.
