ABSTRACT This work focus on the effect of different contents of Cu on microstructure and properties of Al–Zn composite coatings. The SEM and EDS were used to analyse the microstructure and composition of the coatings, and the deposition efficiency and porosity of the coating were calculated. The results show that the coatings have low porosity and uniform structure. The hardness, electrical conductivity and corrosion resistance of the coating were measured, and the results showed that the addition of Cu can improve the hardness, electrical conductivity and corrosion resistance of the coating but reduce the deposition efficiency of the powder.

冷喷涂不同Cu含量的Al-Zn-Cu复合涂层的制备与表征

摘要 本工作重点研究不同Cu含量对Al-Zn复合涂层组织和性能的影响。利用SEM和EDS分析涂层的微观结构和成分，计算涂层的沉积效率和孔隙率。结果表明，涂​​层孔隙率低，结构均匀。对涂层的硬度、电导率和耐蚀性进行了测量，结果表明Cu的加入可以提高涂层的硬度、电导率和耐蚀性，但降低了粉末的沉积效率。
