“…6(b)). Although the carbon content in TiAlN/8.5 at%C coating is similar to that of Ti-Al-N-C coatings in the range of 9.5 to 13.5%C reported by M. Steuber et al, 12) the microstructure revealed by TEM was completely different. Instead of partially diffused SAED pattern and ''fibre-like structure (average column diameter is about 50 nm for 13.5%C coatings)'' found by them, the diffused broad SAED pattern with dispersed nano-crystallites in amorphous matrix was observed in this study.…”

“…10) XPS analysis of these films showed that some carbon atoms bound as (Ti,Al)-C 7,12) or (Ti,Al)-CN. 13) These results indicate that the hardness of TiAlN/a-C coatings is affected not only by microstructure but also by the existence of carbides and the relationship between the microstructure and mechanical property of TiAlN/a-C coatings has not been elucidated satisfactorily.…”

“…Nanocomposite coatings consisting of different bonding structure have possibilities of synthesizing a surface protection layer with an unusual combination of mechanical and tribological properties such as high hardness and toughness, superior wear resistance and low frictions. 2) To attain this goal, TiC/a-C, [3][4][5][6] TiAlN/C or CrAlN/C coatings [7][8][9][10][11][12][13][14][15] have been prepared by various methods, including arc ion plating (AIP), closed field unbalanced magnetron sputtering (CFUBMS), plasma enhanced chemical vapor deposition (PECVD). However, only a limited amount of research on TiAlN/a-C coatings prepared in the mixture of Ar and N 2 gases without hydrocarbon gas has been conducted.…”

TiAlN/a-C nano-composite coatings were synthesized by a reactive co-sputtering process to investigate the effects of sputtering conditions on the microstructure and mechanical properties. Coating films were deposited on square plates of Si and high speed steel (ANSI M2) by the cosputtering of TiAl (pulsed-d.c. sputtering) and C (d.c. sputtering) targets using a ''Facing Target-type Sputtering'' system at an atmosphere with a mixture of Ar and N 2 but without hydrocarbon gas. The structure of the coatings was investigated by means of XRD, XPS and HRTEM with GIF (Gatan Imaging Filter). Mechanical properties of coating films were measured by a submicron indentation system. Though TiAlN and a-C coatings showed hardness of about 32 and about 10 GPa, respectively, TiAlN/a-C coatings containing 4.6 at% of C showed higher hardness of 43 GPa. The energy filter images depicted that a change of contrast in the zero-loss image corresponded to nanometer-size of Ti agglomerates in Ti map. C1s spectrum in XPS analysis revealed that carbon in the coatings was bounded as C-C and C-N without bonding of Ti-C or Al-C. These results indicated that the TiAlN/a-C nano-composite coatings consisted of complicated mixture of nanocrystalline Ti-Al-N phase and a-C phase (including C-N bonding).

Abstract. The aim of this work was to investigate mechanical and cutting properties, as well as the nature of wear and failure of carbide cutting tools with modifying coatings of two types: nanostructured multi-layered coating Zr-ZrN-(ZrCrAl)N, applied through the use of the technology of filtered cathodic vacuum arc deposition, and multi-layered nano-structured and gradient coating Ti-(TiAl)N-(TiAl)N, applied through the use of the technology of LARC ® (Lateral Rotating Cathodes). It is found out that the both types of coatings under test significantly improve tool life of a carbide cutting tool. The studies of mechanisms of wear and failure of carbide tools with coatings under test, conducted at macro and micro levels, have identified their major differences and revealed their most preferable field of application. The carbide tools, equipped with cutting inserts with the nano-structured multi-layered coating under study, provided a significant increase in cutting properties (tool life) of the tool in comparison with the uncoated carbide tool and in comparison with the reference carbide tool with TiN coating. The tool with the coating Ti-(TiAl)N-(TiAl)N under study demonstrated the increased wear resistance during 30-35 min of cutting, and then, the process of coating failure and tool wear was sharply intensified. For the tool with coating Zr-ZrN-(ZrCrAl)N, the tests revealed more evenly-balanced wear during the whole operating time between failures. It should be noted that NMCC Zr-ZrN-(ZrCrAl)N are substantially thinner, and that fact predetermines their better resistance to failure because of crack formation, and the technology of its generation is more cost-effective.

Stoichiometric TiZrCN, TiNbCN, and TiSiCN coatings, with Zr, Nb, or Si as alloying elements, were deposited on Si and M2 high speed steel substrates by the cathodic arc technique in a mixture of N2 and CH4 gases. Coatings with a C/N ratio value of about 0.5 have been prepared and comparatively investigated for elemental and phase composition, texture, adhesion, and anticorrosive properties. All coatings consisted of fcc solid solutions, with an (111) preferred orientation. The addition of either Zr, Nb, or Si in the basic structure of TiCN coatings resulted in adhesion enhancement (critical loads in the range 20–30 N) and increased corrosion resistance, as tested in 3.5% NaCl solution.
