Abstract

U ovom radu definiran je pojam difuzije te su navedene i pobliţe objašnjene vrste difuzijskih procesa. TakoĎer su prikazani različiti mehanizmi difuzije karakteristični u metalima i metalnim legurama te su navedene direktne i indirektne metode mjerenja difuzije. Definiran je koeficijent difuzije kao mjera brzine difuzije te je opisana njegova ovisnost o temperaturi, tlaku i obliku kristalne rešetke. Navedeni su Fickovi zakoni difuzije za stacionarno i nestacionarno stanje te su istaknuti primjeri primjene difuzije u metalurgiji.

Abstract (english)

In this paper, the term diffusion is defined and the types of diffusion processes are listed and explained in more detail. Various diffusion mechanisms characteristic of metals and metal alloys are also presented and direct and indirect methods of diffusion measurement are given. The diffusion coefficient is defined as a measure of the diffusion rate and its dependence on the temperature, pressure and shape of the crystal lattice is described. Fick's laws of diffusion for stationary and non-stationary states are given, and examples of applications of diffusion in metallurgy are highlighted.
