AbstractProperties of polycrystalline metal alloys such as endurance and solidity as well as their conservation under high and low temperatures, are determined by the chemical composition, polycrystalline structure of the alloy and mostly by the grain boundaries peculiarities. Adsorptive film-type layers of alloying and extrinsic components, which develop on the grain boundaries as a result of a surface segregation and diffusion, treated as a third component or a body, which acts as lubricant between two interacting grains, thus making grain sliding and material destruction processes easier. During our research we have evaluated the friction coefficient between polycrystalline iron grains, which have different tentative segregant layers on their surfaces. We have also revealed the friction coefficient’s periodic dependence on the segregant’s atomic number. Was determined out that the higher the friction coefficient is, the tighter the link between the polycrystalline materials can be observed.
