The structural and phase transformation of microarc oxidation (MAO) coatings on 6061 aluminum alloy at 300∘C/3[Formula: see text]MPa steam were evaluated. After 10 days steam corrosion, the weight loss of coated alloys with 15[Formula: see text][Formula: see text]m and 75[Formula: see text][Formula: see text]m thickness was only about 1/10 and 1/50 of weight gain of bare alloy, respectively. The [Formula: see text]-Al2O3 and [Formula: see text]-Al2O3 phases in the MAO coatings were stable at 300∘C/3[Formula: see text]MPa steam, but many fine needle-like or brick-like boehmite crystalline particles also appeared on coating surface. The boehmite had a large influence on the permittivity of coatings at low frequency. The MAO treatment on 6061 aluminum alloy improved its corrosion resistance at high-temperature and high-pressure steam.

ABSTRACTHybrid solar receivers utilizing both photovoltaic cells and thermal collectors are capable of collecting the entire solar spectrum for use in energy systems. Such systems provide efficient solar energy conversion using PV in addition to dispatchability through thermal storage by incorporating a thermal collector in conjunction with the PV. Proposed hybrid systems typically invoke spectrum splitting so to redirect photons optimized for PV electric conversion to a cell while non-PV efficient photons are directed to a thermal absorber. This work discusses a hybrid system with a selective solar filter using a suspended nanoparticle fluid to directly absorb non-PV photons. Non-absorbed photons pass through the filter and impact the PV. Choice of nanoparticles in the fluid allow absorption and transmission of specific wavelengths. Nanoparticles were chosen based on optimization simulations for a bandpass filter to a cSi solar cell. The synthesized fluid has been experimentally characterized to show the effects of high temperature on nanoparticle stability and optical properties. Thermodynamic modeling of the system suggests solar to electric efficiency of the total system is 23.2% if all thermal energy is converted to electricity through an organic Rankine cycle (ORC). However, high temperature generation could be used for industrial process heat at a specific temperature by changing parameters such as absorbed energy and flow rates. Furthermore, a prototype is being developed with 14x concentration to demonstrate the technology on-sun with initial testing targeted for the 2nd quarter of 2016. Overall, the hybrid nanoparticle filter concentrating solar collector can be modified to fit a variety of applications through easily changeable parameters in the system.
