This paper attempts to identify key factor(s) for highly reflective silver (Ag) coatings. Investigation was made over the crystal orientation and surface roughness, using several types of surfaces, including electroplated Ag polycrystal films, physical vapour deposited polycrystal Ag films, and single crystal Ag foils with different crystal orientations. In each type of the surfaces, surface roughness was varied so that, for different combinations of crystal orientation, roughness would elucidate the key factors towards highly reflective Ag coatings. It is found that surface roughness plays a critical role in determining the reflectance, while the crystal orientation has negligible effect. The mean reflectance and one-way ANOVA analysis indicate that the single crystal Ag foils with three orientations performed statistically the same in the same roughness group at significance level = 0.05. Moreover, correlation between the surface reflectance and surface roughness has been proposed for the benefit of coating design. Refection data obtained from the polycrystalline silver samples are used to verify the accuracy of the proposed correlations. It was observed that the development surface area ratio, , is a better roughness indicator in predicting the reflectance of polycrystalline silver films than the arithmetic average roughness, .

“…It is known that electroplating solutions are able to produce bright deposits which consist of crystallites smaller than the wavelength of visible light, 0?4 mm, 41,42 and having oriented grain structure. 43 A small grain size is a necessary, but not a sufficient, condition for brightness; likewise not all fine-grained deposits are bright. It has been found that the brightness depends on the degree to which morphological components of the surface and electrodeposits are in the same plane.…”

Cobalt electrodeposits have been produced from two types of baths. In the bath containing cobalt sulphate, cobalt chloride and boric acid, saccharin is found effective as a brightener additive. In the bath containing cobalt sulphate, potassium chloride and potassium citrate, thiourea is found to be effective as a brightener additive. Results of solution characteristics such as conductivity of the electrolytes, cathode current efficiency and rate of deposition are compared. The effect of additives on brightness, roughness, orientation of the crystal, grain size and surface morphology of the cobalt deposits are reported. The X-ray diffraction pattern obtained for electrodeposited cobalt showed a polycrystalline nature with hexagonal close packed structure. A smooth uniform and pore free surface was observed under scanning electron microscopy and atomic force microscopy analysis. Potentiodynamic polarisation and electrochemical impedance measurements in sodium chloride solution showed that a higher corrosion resistance was observed for the deposit from the second type of bath containing an additive.

“…Membrane morphology was analysed firstly by visual observation of the brightness [36] and secondly using SEM images. These images were obtained after Cu plating, after alloying and after the permeance tests, in order to check how the surface changed throughout the entire process.…”
