Abstract
The paper presents the results of the study of ion irradiation on the properties of multi-element plasma coatings. The coatings were bombarded by argon ions using heavy current ion source with a hollow cathode. After ion irradiation, the structure and physical properties of the coatings change, however, the nature of the changes is different for different coatings. To predict the behavior of the coating exposed to irradiation is virtually impossible. Therefore, structural studies and investigation of physical properties of the coatings to determine their functional characteristics are to be conducted.
Highlights
The main effects of ion irradiation on the properties of the coatings occur at the stage of their emergence due to stress relaxation in the region of ion impact and restructuring of the crystal structure [1,2,3]
Point defects and active adsorption centers are formed on the surface
As a result of these two processes, the amount of nucleation centers becomes equilibrium, and it may be changed through varying parameters of ion irradiation
Summary
The main effects of ion irradiation on the properties of the coatings occur at the stage of their emergence due to stress relaxation in the region of ion impact and restructuring of the crystal structure [1,2,3]. The effect of ion irradiation on films and coatings has been investigated in a number of studies [3,4,5,6,7,8,9,10,11]. Objects and experiment techniques In the experiments, we used composite cathodes Cr-Mn-Si-Cu-Fe-Al, Zn-Al, Zn-Cu-Al, Mn-Fe-Cu-Al and Al-Fe produced through induction melting The atomic force microscope NT-206 was used to perform a nanoscale study of the surface coatings
