Abstract
Napetost površine nastaje zato jer je površinski sloj tekućine rjeđi od njene unutrašnjosti. Zbog toga molekule nisu na ravnotežnim udaljenostima, nego su međusobno udaljenije, pa među njima djeluju privlačne sile s težnjom da smanje razmak molekula. Ove privlačne sile stvaraju površinsku napetost. Površinska napetost se smanjuje povećavanjem temperature, jer povećani nered potiče povratak udaljenih molekula natrag na površinu. Budući su fizikalna svojstva poput viskoznosti, gustoće i površinske napetosti talina vrlo važna u mnogim metalurškim procesima, u ovom radu je definiran pojam površinske napetosti te njena ovisnost o temperaturi. Također je dan pregled praktičnih primjera površinske napetosti te metoda odreĎivanja površinske napetosti tekućina i talina.
Abstract (english)
Surface tension occurs because the surface layer of fluid is rarer than its interior. Therefore, molecules are not in equilibrium distances, but are more distant to each other, so between them act attractive forces with the tendency to reduce the distance between the molecules. These attractive forces create surface tension. The surface tension is reduced by increasing the temperature, because the increasing disorder encourages the return of runaway molecules to the surface. Since the physical properties such as viscosity, density and surface tension of melts is very important in many metallurgical processes, this paper defined the concept of surface tension and its dependence on temperature. It also gives an overview of practical examples of the surface tension and the methods of determining the surface tension of liquids and melts.
