The relationship between the light-reflecting property generally referred to as the brightness, and structure of electrodeposits has been the subject of many investigations. These studies have led to two theories. One theory states that electrodeposits are bright if their microstructure consist of crystallites smaller than the wavelength of visible light, i.e., smaller than 0.4 micrometers. At the same time, for the surface to be bright, a roughness of less than 0.15 micrometers and 0.025 micrometers is required. The second theory states that the more oriented the grain structure, the brighter the deposit, the bnghtnes being dependent on the degree to which the morphological components of the surface of electrodeposits are in plane. On the other hand, it has been found that a major fraction of mirror-bright (Ni) metal electrodeposits exhibit no preferred orientation. Hence, both theories do not hold. The conditions which must be fulfilled in order for the metal surfaces to exhibit mirr...or brightness have not been classified and systematized yet. Progress in the investigation of the structure of bright metal surfaces has accelerated recently, thank to the development of the Scanning Tunnelling Microscopy (STM) and Atomic Force Microscopy (AFM) techniques. It has been shown by these techniques that the reason of the mirror brightness of electropolished copper surfaces might be that large parts of the surface consists of small, flat and mutually parallel metal crystals, which exhibit smootthness on the atomic level. For this reason, it was considered necesarry to examine whether this conclusion about the structural features of electropolished mirror bright metal surfaces is also valid and for bright metal coatings obtained by electrodeposition.
