Effectiveness of using of titanium diboride-based coatings to improve wear resistance of end radius milling cutters when processing of Inconel 718 alloy

End mills with TiAlSiN, TiB2 and TiAlSiN—TiB2 coatings are tested for durability. The features of tool cutting edge wear are determined. The mechanisms of contact interaction of coatings with the material under processing are established, and the results of tribological tests are presented. The chemical compositions of the coatings under study are determined using X-ray photoelectron spectroscopy.
