Review of Methods for Obtaining Hardening Coatings

The paper is devoted to the consideration of existing methods of deposition of hardening coatings. The paper discusses the relationship between the coating deposition process and the control circuit for the ion current density and energy control. The analysis of deposition methods is carried out and on the basis of this analysis the CIB deposition method of hardening coatings is selected. The authors studied the features of each of the considered methods, which made it possible to identify the main advantages and disadvantages. Based on the data obtained, it шs revealed that for equal-thickness coatings, it is necessary to use control circuits for the ion current density and energy.
