在钢板上制备太阳选择性吸收表面的工艺及性能研究

THE PREPARING PROCESS AND PROPERTIES ANALYSIS OF SOLAR SELECTIVE ABSORBING SURFACES ON MILD STEEL

本文报道了采用交流氧化方法,在冷轧低碳钢板上制备太阳选择吸收表面的工艺过程,对表面膜的光谱选择吸收率α和红外发射率e、抗紫外光老化及耐潮湿性能进行了测试和评估。此外,利用电子显微技术、穆斯堡尔谱和俄歇能谱对表面的形貌及组成结构进行了观察和分析。

This paper introduces the solar selective absorbing surface preparation process by AC oxidation method on cold-rolled mild steel plate.Its Solar absorptance a and thermal emittance e durability,ageing resistance to humidity have been tested and eva-luted.In addition to the micrography,stracture and constitution of selective absorbing surface have been observed and analyzed by Scanning Electron Microscope(SEM),Auger Electron Spectroscopy(AES) and Mossbaur Spectroscopy.The results show that the AC oxidation method can meet the needs of solar low temperature utilization.
