“…For coating deposition, a vacuum-arc VIT-2 unit was used, which was designed for the synthesis of coatings on substrates of various tool materials [1][2][3]13]. The unit was equipped with an arc evaporator with filtration of vapour-ion flow, which in this study were named as filtered cathodic vacuum arc deposition (FCVAD) [1][2][3][4]13,14], which were used for deposition of coatings on tool of significantly reduces the formation of droplet phase during the formation of coating.…”

“…Nano-structured multilayered composite coating Ti-TiN-(NbZrAl)N was selected as an object of the study due to the following factors [1,3,4]: ■ ■ a good combination of high hardness and resistance to brittle fracture, which was shown by the coatings on the basis of system (NbZrAl)N during earlier studies; ■ ■ a role of coating Ti, confirmed during earlier studies, as an optimal adhesive sublayer that provides good adhesion both between tool substrate and coating and between adhesive and intermediate layers of coating; ■ ■ good results in tool life of metal cutting tool with the above coating shown during tests conducted earlier [1,3,4]. One of the objectives of this research was to study failure mechanism of nano-layered multi-component systems operating under conditions of high thermal and mechanical stresses arising in the cutting zone.…”

the paper studies mechanical properties (in particular, adhesion characteristics), as well as wear and failure pattern of nano-structured multilayered composite coating ti-tin-(nbzrAl)n. cutting properties of a carbide tool with the above coating are studied in turning of steel c45, in comparison with an uncoated tool and a tool with reference coating tin. it was found that tool life of the tool with the coating under study is 2.7-3.6 times higher than tool life of the uncoated tool and 1.8-2.2 times higher than that tool life of the tool with coating tin. the conducted microstructural studies have shown a significant difference in wear and failure mechanisms and, in particular, in mechanisms of cracking, for the coating under study and the coating tin. Failure mechanism of coating in the course of the study of strength of adhesion bonds is consistent with its failure mechanism during the study of cutting properties.

Nanocomposite coating is a coating with measurements of grain size or individual layers which could be less than 100 nm and it offers enriched durability and performance. The objective of this article is to present the chemical and mechanical characteristics of nano-coated cutting tools. To improve the machinability and tool life, the cutting tool inserts are coated with nanoparticles of nitride coatings using titanium nitride, titanium aluminium nitride and titanium aluminium nitride with silicon nitride. With the advent of nano composites, a coating of thickness in nanometers has become a reality. The nano coatings are carried out through physical vapor deposition process on thin films, get experimentally tested and are coated on cutting tool insert. These TiN, TiAlN and TiAlN/Si3N4 have been adopted due to their better chemical and mechanical properties. Enrichment of hardness is an important criteria and maximum hardness is obtained through multilayer structurization of composites. In this experimental analysis, the various mechanical properties of thin films like hardness, Young's and reduced modulus of thin films were found through a method called nanoindentation, which was carried out on nine different samples of titanium nitride and the results were interpreted.
