The development of electrodeposited materials with improved technological properties has been attracting the attention of researchers and companies from different industrial sectors. Many studies have demonstrated that the electrodeposition and synthesis of alloys and composite materials assisted by ultrasound may promote the de-agglomeration of particles in the electrolytic solution due to microturbulence, microjets, shock waves, and breaking of Van der Waals forces. The sonoelectrochemical technique, in which the ultrasound probe acts as a working electrode, also has been used for the formation of nanostructures in greater quantity, in addition to accelerating the electrolysis process and eliminating the reaction products on the electrode surface. Regarding the morphological aspects, the acoustic cavitation promotes the formation of smooth and uniform surfaces with incorporated particles homogeneously distributed. These changes have a direct impact on the composition and physical properties of the material, such as corrosion resistance, magnetization, wear, and microhardness. Despite the widespread use of acoustic cavitation in the synthesis of nanostructured materials, the discussion of how process variables such as acoustic power, frequency, and type of ultrasound device, as well as their effects still are scarce. In this sense, this review discusses the influence of ultrasound technology on obtaining electrodeposited coatings. The trends and challenges in this research field were reviewed from 2014 to 2019. Moreover, the effects of process variables in electrodeposition and how these ones change the technological properties of these materials were evaluated.

超声辅助电沉积和合金及复合材料的合成:综述。

具有改进的技术性能的电沉积材料的开发已经吸引了来自不同工业领域的研究人员和公司的关注。许多研究表明,由于微湍流,微射流,冲击波和范德华力的破坏,超声辅助下合金和复合材料的电沉积和合成可能会促进电解液中颗粒的解聚。除了加速电解过程和消除电极表面上的反应产物之外,还用超声波探针作为工作电极的声电化学技术来大量形成纳米结构。关于形态方面 声空化促进形成光滑均匀的表面,使掺入的颗粒均匀分布。这些变化直接影响材料的成分和物理性能,例如耐蚀性,磁化强度,磨损和显微硬度。尽管在纳米结构材料的合成中广泛使用了声空化,但是对于诸如声功率,频率,超声设备的类型以及其影响等工艺变量的讨论仍然很少。从这个意义上讲,这篇评论讨论了超声技术对获得电沉积涂层的影响。回顾了2014年至2019年该研究领域的趋势和挑战。此外,
