“…Oxidation resistance of TiAlN is governed by higher chemical stability, in comparison to binary nitrides like TiN and AlN coatings [1][2][3][4][5][6]. In this material, TiN is constituted as rock salt structure with metallic conductivity at room temperature [7].…”

“…In contrast, soft phase like AlN is useful for low friction coefficient. Moreover, wear and friction behavior are complex phenomena when several composition and phases get involved in the TiAlN coating [1,9]. Given the complexity of tribochemical interaction and multitude of phases appearing at the sliding interfaces, the plastically deforming wear mechanism becomes quite complex and deformation is largely dependent on the nature of the sliding body [10].…”

“…The influence of Si addition to CrAlN structure has been recently reported using XANES [3,4] and we recently correlated nanoindentation with nanoimpact analysis in CrAlSiN coatings [5]. Different types of hard coatings such as AlTiN and TiAlCrN coatings have been characterized using nanoimpact testing [6,7]. This technique is a powerful experimental method to find out fracture behavior of hard coatings and directly determine properties such as fracture, ductility to failure that cannot be directly determined through nanoindentation [6,8].…”

Statistical studies involving the fracture behavior of coatings can play an important role in the mechanical analysis of films employed in the hard coating industry. In this study, Nanoimpact tests using a cube corner indenter were carried out in various CrAl(Si)N coatings for the quantitative assessment of properties of coatings like non-catastropic failure time and catastrophic failure time. These parameters decrease in value as silicon is incorporated in coatings, showing that this addition results in a decrease in ductility. Scanning electron microscope images were taken to the analyzed coatings exhibiting the residual imprints after nanoimpact test that were correlated with the fracture behavior of CrAl(Si)N coatings.

“…Nitrides such as TiN and CrN have been successfully deposited on an industrial scale on different machine tool components as wear and corrosion resistant layers, e.g. for cutting, moulding and forging (Suresha et al, 2006). However, industrial applications of the single layer and multilayer TiAlN coatings synthesized by physical vapor deposition (PVD) are increasing rapidly due to its advanced tribological properties and high temperature oxidation resistance (Chang and Wang, 2007).…”

Purpose -The purpose of this paper is to examine mechanical and metallurgical properties of AlTiN coating HSS materials in detail. Design/methodology/approach -In this study, high-speed steel (HSS) parts were processed by the way of machining and were coated with AlTiN on physical vapour deposition (PVD) workbench at approximately 6508C for 4 h. Tensile strength, fatigue strength and hardness tests for AlTiN coated HSS samples were performed. Samples were also analyzed by energy dispersive X-ray analysis (EDS), X-ray diffraction (XRD) and scanning electron microscope (SEM). The results were compared with uncoated HSS components. Findings -It was found that an amorphous aluminium-oxide layer emerges on surface of parts by AlTiN coating. This layer prevents further oxide formations. The coating thickness of AlTiN-coated sample is between 1,530 and 1,558 mm. Compared to uncoated HSS, AlTiN coated HSS gives higher performance.Research limitations/implications -It would be interesting to search different coatings for cutting tools. It could be the good idea for future work concentrated wear properties on tool materials using different coatings. Originality/value -This paper provides information on mechanical and metallurgical behaviour of AlTiN coated HSS materials and offers practical help for the researchers and scientists working in the coating area.
