Abstract The present work is a continuation of our earlier work in which high entropy alloy MoNbHfZrTi is used as a raw material to prepare solar absorber coating. In this work, we have further investigated a novel Al/MoNbHfZrTiN/MoNbHfZrTiON/SiO2 multilayer color solar selective absorbing coating, including structure, optical properties, thermal stability and corrosion performance. The results of TEM and XRD indicate that the Al film has nanocrystalline nature and MoNbHfZrTiN, MoNbHfZrTiON and SiO2 are amorphous structure. The results of the mapping confirm the thickness of each layer and distribution of elements. The simulation of optical constants (n and k values) are carried out by CODE software, the results of which indicate that the n and k values decrease from substrate to surface. Neutral salt spray test is preformed to measure the ability of anti-corrosion, which indicates the coating has a good optical performance in 3.5% NaCl solution for 24 h.

一种新型高熵合金 MoNbHfZrTi 基太阳能吸收涂层的双抗反射涂层的进一步研究

摘要 目前的工作是我们早期工作的延续，其中高熵合金 MoNbHfZrTi 被用作制备太阳能吸收涂层的原材料。在这项工作中，我们进一步研究了一种新型的 Al/MoNbHfZrTiN/MoNbHfZrTiON/SiO2 多层彩色太阳能选择性吸收涂层，包括结构、光学性能、热稳定性和腐蚀性能。TEM和XRD结果表明Al薄膜具有纳米晶性质，MoNbHfZrTiN、MoNbHfZrTiON和SiO2为非晶结构。映射的结果确认了每层的厚度和元素的分布。光学常数（n 和 k 值）的模拟由 CODE 软件进行，其结果表明 n 和 k 值从基板到表面递减。
