Surface morphology, appearance & tribology of electrodeposited tin films

The appearance of electrodeposited tin has been classified as matte, satin-bright and bright. Obviously, this ``appearance{''} classification is qualitative and subject to interpretation,It would be useful ifa quantitative method could be developed, based on reflectivity (glossiness) to describe the surface appearance. Moreover, it would be fundamentally interesting to understand the relationships among surface ``glossiness,{''} surface morphology, the structure of the electrodeposited film, and its effects on tribological behavior, such as the coefficient of friction and wear resistance.
