“…During the scratch measurements it was noticed that heat influences the plastic and chip deformation of the layer. Thermal stability of multilayer Ti 1-x Al x N/TiN formed on two PM-HSS (S390PM, S290PM) substrates were investigated by T. Weirather et al [12]. Temperature of the substrate during multilayer coating formation was between 373°C-575°C.…”

Abstract. Turning tools come in different shapes and sizes, geometry, base material and coating, according to their destination. They are widely used both for obtaining parts and for machinability tests. In this paper a short review about high-speed steel (HSS) turning tools and their coatings is presented. Hard coatings formed on the tool material should be functional depending on the tool final application. Requirements for hard coatings and technological problems for layer formation on the real cutting tool are discussed. Techniques and production of hard coatingsIn a statistical study made for the year 2013 [1] the 16.33 billion US-Dollars estimated industry of cutting tools includes 39% milling tools followed by 30% of turning tools, with an annual growth assumed to be 4-5%. The same study shows that in 53% of the cases, the cutting tool substrate is represented by cemented carbide and in 20% of the cases by highspeed steel (HSS).Coatings on cutting tools are widely spread due to the improvement they provide during the cutting process. In the early 2000's made statistic 50% of HSS tools, 85% of carbide tools and 40% of super-hard tools used in industry were coated [2]. Due to the more complex phenomenology which accompanies the intermittent cutting process, in this study only coatings of HSS turning tools will be treated.The use of coatings is expected to yield a better protection of the tool against abrasion and adhesion, diffusion, oxidation and to produce a heat barrier for the intensive heat flowing from the cutting area into the tool material [3], thus increasing productivity and tool's life. However, regarding the heat insulation the opinions are divided, as in the paper [4] it was proven that the coatings of continuous cutting tools are not able to insulate the substrate.Mainly, depending on the method and the coating structure, the same coatings can be applied to both HSS and carbide tools, each substrate having its advantages and disadvantages according to the cutting application. The properties of the tools surface should be improved according their novelty, application and to achieve higher productivity for the manufacturing process. Depending on the turning tools destination various hard coatings can be formed on its surface. The shape of the turning tool is usually not complicated, thus techniques like physical or chemical vapor deposition for layer formation are applied. Hard *

“…Nonetheless, the application of titanium nitride (TiN) thin films is not limited to machining tools. Due to its mechanical, optical and electrical properties, TiN has widespread applications in the automotive, aerospace, microelectronics and also in sanitary industries [6][7][8][9][10][11][12][13][14][15]. TiN films have been also proposed for application in nuclear reactors as coatings on nuclear fuel cladding alloys.…”

Titanium Nitride (TiN) films were obtained using the grid-assisted magnetron sputtering deposition technique on Al substrates in two conditions: under constant and variable nitrogen concentration along the thin solid film thickness. The formation of a film with variable N concentration (herein referred as graded film) was confirmed using energy filtered transmission electron microscopy, X-ray photoelectron spectroscopy and grazing incidence X-ray diffraction. The TiN thin films microstructures were also analysed using scanning and transmission electron microscopies (SEM and TEM). The viability of synthesizing TiN thin films with variable N concentration is herein proposed as an alternative method for tailoring the properties of such functional coating materials.

“…Multilayer coatings of TiN and TiAlN have been widely studied since they enhance properties such as hardness, wear resistance, and corrosion resistance [19,[28][29][30][31][32][33]. The reason of increased hardness and wear resistance in multilayer structures was attributed to the dense and fine grain structure achieved by the interruption of the columnar grain structure due to nucleation of the successive layer, leading to large interfacial area [19].…”

In an attempt to develop an accident-tolerant fuel (ATF) that can delay the deleterious consequences of loss-of-coolant-accidents (LOCA), multilayer coatings were deposited onto ZIRLO ® 1 coupon substrates by cathodic arc physical vapor deposition (CA-PVD). Coatings were composed of alternating TiN (top) and Ti 1-x Al x N (2-layer, 4-layer, 8-layer and 16-layer) layers. The minimum TiN top coating thickness and coating architecture were optimized for good corrosion and oxidation resistance. Corrosion tests were performed in static pure water at 360º C and 18.7 MPa for up to 90 days. The optimized coatings had no spallation/delamination and had a maximum of 6 mg/dm² weight gain, which is 6 times smaller than that of a control sample of uncoated ZIRLO ® which showed a weight gain of 40.2 mg/dm². The optimized architecture features a ~1µm TiN top layer to prevent boehmite phase formation during corrosion and a TiN/TiAlN 8-layer architecture which provides the best corrosion performance.
