摘要

电子显微镜对电结晶初期的黑镍涂层薄膜进行了研究。Ni-Zn-S、Ni-Zn-Fe-S、Ni-Cd-Zn-Fe-S和Ni-Mo-Fe-Mn是四种不同类型的黑色涂层。大多数实验采用硫氰酸铵作为发黑剂，在硫酸盐浴中电结晶。在不同类型的晶体中观察到有趣的形态和晶体生长模式。铁的引入显著地改变了晶体的生长特性。这些薄膜的机械和光学吸收特性可以从晶体的生长行为来理解。

Electron microscopic investigations on the morphology and crystal growth characteristics of black nickel thin films

SummaryElectron microscopy studies were made on thin films of black nickel coatings during the initial stages of electrocrystallisation. Ni-Zn-S, Ni-Zn-Fe-S, Ni-Cd-Zn-Fe-S, and Ni-Mo-Fe-Mn were the four different types of black coatings examined. The coatings were electrocrystallised from sulphate baths with ammonium thiocyanate as the blackening agent in most experiments. Interesting morphological and crystal growth patterns were observed for the different types. Introduction of iron significantly alters the crystal growth characteristics. The mechanical and optical absorption properties of these films can be understood from the crystal growth behaviour.

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
