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.

“…The most probable mechanism of failure of a ceramic tool is brittle fracture of cutting wedge [1][2][3][4][12][13][14][15]. This occurs because of the lower brittle strength of the ceramic tool material as a b compared with the corresponding characteristics for carbide material.…”

“…In this respect, large-scale studies are currently undertaken to improve the properties of cutting ceramic through deposition of functional coatings. The wide use of this technology for dry high speed shape-generating machining provides the significant cost-efficiency while reducing negative impacts on the environment and personnel health [14][15][16][17][18][19][20][21][22][23][24]. In contrast to carbide and high-speed steel, for which the use of modifying coatings provides positive effects, the benefits of coatings for ceramic cutting tools are not always obvious.…”

“…Therefore, ceramic tools are very sensitive to thermal cycling loads and are characterized by an increased tendency to micro/macro-brittle failure at contact stresses higher than 900-1000 MPa, which predetermines the very narrow scope of application (K01-K10, P01-P10) [1,3]. An effective method for overall improvement of physical and mechanical properties of cutting ceramic is the deposition of modifying functional coatings on the working surfaces [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Thus allowing a control of contact processes in order to change thermomechanical strain of the cutting edges and the nature of wear.…”

This paper presents the results of development of nano-scale multi-layered composite coatings, that modifies contact processes of ceramic cutting tools in order to reduce the brittle fracture of cutting edges and to ensure balance wear of tool contact areas during dry high-speed cutting of hardened steels. The technology of filtered cathodic vacuum arc deposition was used to produce modifying coatings. This technology provided the possibility to form nano scale multi-layered composite coatings (NMCC) with improved physical and mechanical properties and adhesion strength to ceramic substrate. This work used thermodynamic criteria to evaluate the selected composition of NMCC, and studied crystal-chemical, physical, mechanical and cutting properties and wear mechanisms of NMCC. The Ti-TiAlN-ZrNbTiAlN coating structure was deposited on various ceramic Al2O3, Al2O3-TiC and Si3N4 substrates. It is shown that wear mechanism of a ceramic tool with developed coatings is connected with adhesive-fatigue processes, and the development of wear centres on rake and flank faces of the tool is of balanced nature without typical brittle chips. It was found that during high-speed longitudinal turning of hardened steel X153CrMoV12, the tool life of a ceramic tool of Al2O3-TiC -Ti-(TiAl)N-(ZrNbTiAl)N was up to 1.5 times longer than the tool life of uncoated tools and up to 1.3 times longer than the tool life of tools with PVD coating Ti-TiAlN.

“…An experimental analysis was done on different MMCs and it was found that metal cracks always prompted for the period of the matrix crossing points and also based on the bonding of the particle [18][19][20][21] . Similarly, Nano mixed materials and lubricants are used as fillers and nano agents in nanocomposites and nano fluids to change the different properties and heat transfer rates in different fields like mechanical, aeronautical, electrical and electronics [22][23][24][25] . Similarly, polymer reinforced nanocomposites with inorganic nanoparticles are much better due to their light weight, homogeneity, low cost and simple physical properties [26][27][28][29] .…”

Aluminium matrix composites have more research focus due to its outstanding properties of specific strength, superior wear resistance and low thermal expansion. The main objective of this research is to estimate the effect of friction stir processing on microstructure and properties of aluminium alloy with tungsten carbide metal matrix insitu composite by low-cost stir casting technique. Friction stir processing is used to modify the cast microstructure of aluminium alloy 2024 with tungsten carbide metal matrix composite. The fabricated composite specimens were subjected to a series of mechanical and microstructural analysis. The observed results were compared with the results of base alloy material. Scanning electron microscope, optical microscopy and micro hardness test were carried out to analyze the microstructure and the dispersion of the reinforced particles in the composite alloy specimens. From the results it was found that, the mechanical properties like hardness value increases due to surface modification when compared with the base aluminium alloy.
