Abstract
The tribological behavior of Ni/Sn multilayer composites was studied. Composites with varied layer thickness and tin volume fraction were prepared by electrodeposition. The coefficient of friction and wear rate of these composites were characterized by pin- on- disk and block- on- ring tests. Both results suggested that soft tin acted as a solid lubricant between the contacting surfaces. Tin-rich films were detected on both the specimen and the steel wear pair surfaces, and wear resistance greatly depended on the thickness, area coverage, composition, and stability of this interfacial film. Specimens with a lower tin content and/or a thinner layer spacing exhibited enhanced wear resistance compared to those with a higher tin content and/or thicker layers. This was attributed to both the solid-lubricating effect of the tin and the enhanced mechanical properties of the multilayered composites.
