英文摘要Aiming at the encapsulation of copper sphere as phase change material for high temperature waste heat recovery, the copper macrocapsules were prepared through a novel chromium plating method. The 100 microns chromium layer coated on copper sphere is dense and uniform and the bond between copper and chromium is good. The mechanism of chromium plating was also analyzed. The thermal properties and performance of the as-prepared macrocapsules were tested by Differential Scanning Calorimeter (DSC) and thermal cycle experiments. The phase change temperature is 1075 degrees C and phase change enthalpy is 153 J/g. Failure mechanism of copper macrocapsule during thermal cycles was investigated. The results show that the duration of the copper macrocapsule against thermal cycles could be enchanced by improving the oxidation resistance of chromium layer, increasing chromium layer thickness, and reducing the diameter of copper sphere.
