Abstract

Abstract

To evaluate the nature of the low gloss properties of Al-Sr10, X-ray diffraction, X-ray energy dispersive spectroscopy, face scan elemental analysis, 8−14 μm infrared emissivity, gloss, and 400−760 nm visible reflectance tests are performed on the material. The Al-Sr10 filler is prepared by high-energy ball milling, and changes in the components, morphology, and optical properties of the Al-Sr10 filler with the ball milling time are evaluated by scanning electron microscopy. The results show that the surface of Al-Sr10 is easily oxidized to form gray-black strontium oxide, and the effect of strontium in the solid solution leads to the extinction of the material. The components of the Al-Sr10 filler do not change with the ball milling time, and the lamellarization, emissivity, and gloss properties of the material increase with time. The degree of lamellarization of the filler after 15 h of ball milling is high, the emissivity is as low as 0.123, and the gloss is as low as 3.8.
