| Abstract | Abstract : Friction and morphological studies were conducted with magnetic tapes contacting a Ni-Zn ferrite hemispherical pin in laboratory air at a relative humidity of 40 percent and at 23 C. The results indicate that the binder plays a significant role in the friction properties, morphology, and microstructure of the tape. Comparisons were made with four binders: nitrocellulose; poly(vinyledene) chloride; cellulose acetate; and hydroxyl-terminated, low-molecular-weight polyester added to the base polymer, polyester polyurethane. The coefficient of friction was lowest for the tape with the nitrocellulose binder and increased in the order hydroxyl-terminated, low-molecular-weight polyester resin; poly (vinyledene) chloride; and cellulose acetate. The degree of enclosure of the oxide particles by the binder was highest for hydroxyl-terminated, low-molecular-weight polyester and decreased in the order cellulose acetate, poly (vinyledene) chloride, and nitrocellulose. The nature of deformation of the tape was a factor in controlling friction. The coefficient of friction under elastic contact conditions was considerably lower than under conditions that produced plastic contacts. |
