Developed a process of assisted filtered cathodic-vacuum-arc deposition (AFCVAD). We used a special emitter (implantor) to generate Cr, Mo ions with high energy. Such key parameters of coatings as composition, structure, a thickness, hardness, adhesion in relation to a substrate obtained at various energy of chrome ions have been studied. A phenomenological (physical) model of assisted filtered cathodic-vacuum-arc deposition (AFCVAD), allows to predict the properties of the coatings formed on the basis of binary compounds as a function of the relationship Ra, characterizing parameters of ion implantation.

The subject of this study were nano-nanoscale multilayer coatings formed using the process of filtered cathodic vacuum arc deposition in assisting high-energy ions of chromium. We used a special emitter (implantor) to generate chromium ions with high energy. Such key parameters of coatings as composition, structure, a thickness, hardness, adhesion in relation to a substrate obtained at various energy of chrome ions have been studied. It is establish the positive change of key properties of coating deposited on carbide inserts WC/CrC/Co, WC / (Co-Re), TiC/TaC/Co at assisted impact of ions Cr at ion acceleration voltage within the range of 10-40 kV. The results of measurement of parameters of coatings with use nanoindentometer are consistent with the X-ray analysis of the stresses in the coating (XSA study). The mechanisms of the effect of modified properties of coatings formed in assisting the filtered cathodic vacuum arc deposition on the properties of the carbide inserts in cutting structural steels and hard-to-cut nickel alloys have confirmed the high efficiency of the deposition process developed coatings and coating compositions.

This article studies the specific features of cathode vacuum arc deposition of coatings used in the production of cutting tools. The detailed analysis of the major drawbacks of arc-Physical Vapour Deposition (PVD) methods has contributed to the development of the processes of filtered cathodic vacuum arc deposition to form nanoscale multilayered composite coatings of increased efficiency. This is achieved through the formation of nanostructure, increase in strength of adhesion of coating to substrate up to 20%, and reduction of such dangerous coating surface defects as macro- and microdroplets up to 80%. This article presents the results of the studies of various properties of developed nanoscale multilayered composite coating. The certification tests of carbide tool equipped with cutting inserts with developed nanoscale multilayered composite coating compositions in longitudinal turning (continuous cutting) and end symmetric milling, and intermittent cutting of steel C45 and hard-to-cut nickel alloy of NiCr20TiAl showed advantages of tool with nanoscale multilayered composite coating as compared to the tool without coating. The lifetime of the carbide inserts with developed NMCC based on the system of Ti–TiN–(NbZrTiCr)N (filtered cathodic vacuum arc deposition) was increased up to 5–6 times in comparison with the control tools without coatings and up to 1.5–2.0 times in comparison with nanoscale multilayered composite coating based on the system of Ti–TiN–(NbZrTiCr)N (standard arc-PVD technology).
