摘要

Nanofluids are enhanced alternatives to ordinary cooling fluids, because these nano-size-powder suspensions show superior heat transfer properties. But there is very little understanding of their wear, erosion and corrosion on surfaces. Because there are no standard tests or instruments for nanofluid tribological effects [2] the authors developed two test-rigs and tested multiple surface-change assessment techniques. Research is presented on a nanofluid (2%-alumina-nanopowder in water, and in water/ethylene glycol solutions) tested on specimens of typical heat-exchanger materials (aluminum and copper. The enhanced surface modifications (when same test is conducted with alumina-nanofluids as compared to the base fluids) were assessed by roughness measurements, by weighing of removed-material, and by optical-microscopy. The obtained results show the suitability of the new testing and assessment techniques and they suggest that nanofluids may lead to substantial erosion-corrosion effects.
