Production of Babbitt Metal Thin Film by Thermal Evaporation Method and Investigation of the Change of Thıs Thin Film With Heat Treatment Time

Abstract

Babbitt alloy is in high demand thanks to its superior corrosion resistance and its hollow-soft structure. Because of these important features, it has been the subject of many studies. In this study, the thin film state of Babbitt alloy will be examined. For this purpose, tin (Sn) based Babbitt alloy on the glass substrate was turned into a thin film by thermal evaporation and these thin films were subjected to heat treatment at 120 oC for different times and the heat treatment effect was examined. The crystal structure of non-heat-treated and heat-treated babbitt thin films was determined by x-ray measurement. It was observed that thin films formed as agglomerations on the crystal structure of tin, and it was observed that the crystallization increased as the heat treatment time increased. Grain-grain boundaries are clearly visible on the coating surface from SEM images. It was determined that the grain sizes decreased in proportion to the heat treatments applied to the thin films at different times and the additive ratios. In addition, it was determined from the EDX results that the oxide layer accumulated in the form of bumps on the surface increased depending on the processing time applied to the thin films obtained and that these layers were composed of tin, antimony and oxygen elements. Finally, it was observed from the AFM images that the roughness value on the thin film surface gradually decreased with the increase of the oxide layer deposited on the surface.
