Autowave processes and self-structures in the formation ion-plasma coatings
The paper discusses the results of a study of microhardness ion-plasma coatings. For coatings used monocomponent and multi-component plasma flows. The deposition was carried out in an atmosphere of argon and nitrogen. Experimental data shows that the microhardness of the coatings quasiperiodically varies across the sample surface. The model of formation of the periodic structure of the coating. The model is based on the occurrence of self-oscillating motions during the formation of the coating due to the concentration gradient component deposited flows.
