“…The addition of Si to TiAlN coatings is known to significantly improve their mechanical properties [71], thus making these types of coatings ideal for the machining of materials such as titanium alloys. Lu et al [82] compares the performance of TiAlN and TiAlSiN-coated tools in the high-speed turning of TC4 titanium alloy. The authors also studied the performance of a gradient TiAlSiN coating.…”

“…It was noticed that there are many research papers about milling operations using the TiAlN-based coated tools. However, for both machining cases, it was found that there is a large interest in the study of the wear performance of these coatings in the cutting of steels [70,71,74,81,83,97,98,100,[111][112][113][114]117], titanium alloys [72,75,76,82,96,115,116] and Inconel [73,[78][79][80]99]. This is due to these alloys being employed in the aeronautical industry, making the study of the machinability of these materials quite interesting.…”

The machining process is still a very relevant process in today’s industry, being used to produce high quality parts for multiple industry sectors. The machining processes are heavily researched, with the focus on the improvement of these processes. One of these process improvements was the creation and implementation of tool coatings in various machining operations. These coatings improved overall process productivity and tool-life, with new coatings being developed for various machining applications. TiAlN coatings are still very present in today’s industry, being used due to its incredible wear behavior at high machining speeds, high mechanical properties, having a high-thermal stability and high corrosion resistance even at high machining temperatures. Novel TiAlN-based coatings doped with Ru, Mo and Ta are currently under investigation, as they show tremendous potential in terms of mechanical properties and wear behavior improvement. With the improvement of deposition technology, recent research seems to focus primarily on the study of nanolayered and nanocomposite TiAlN-based coatings, as the thinner layers improve drastically these coating’s beneficial properties for machining applications. In this review, the recent developments of TiAlN-based coatings are going to be presented, analyzed and their mechanical properties and cutting behavior for the turning and milling processes are compared.

“…So, TiAlN and TiSiN coatings are limited to industrial applications with a high degree of thermal exposure [7,15]. The addition of a fourth element to the coating and the application of multilayer coatings are two of the solutions that have been proposed to solve this problem [15,[21][22][23][24]. On the one hand, different studies have proved that TiAlSiN coatings provide better properties in terms of hardness, oxidation resistance, and thermal stability than TiAlN coatings [22,25].…”

Improved Adhesion and Tribological Properties of AlTiN-TiSiN Coatings Deposited by DCMS and HiPIMS on Nitrided Tool Steels

et al. 2021

Hard coatings, such as AlTiN-TiSiN, deposited by Physical Vapor Deposition (PVD) techniques are widely used in industrial applications to protect and increase the lifetime of industrial components, such as cutting tools, dies, and forming tools. Despite their great properties, such as high hardness and wear and oxidation resistance, they are limited in cases of severe conditions due to the poor adhesion between the coating and the substrate. Duplex treatments have commonly been used to improve the adhesive properties of PVD coatings, especially those of the cathodic arc evaporation type. The purpose of this study is to achieve coatings with the good properties of the Magnetron Sputtering processes but with higher adhesion than that achieved with these techniques, thus achieving coatings that can be used under the most severe conditions. In this work, an AlTiN-TiSiN coating was deposited by a combination of DC Magnetron Sputtering (DCMS) and High-Power Impulse Magnetron Sputtering (HiPIMS) after a gas nitriding pretreatment on 1.2379 and Vanadis 4 tool steels. Mechanical (ultra-microhardness and scratch tests) and tribological tests were carried out to study the improvement in the properties of the coating. Duplex-treated samples showed improved adhesion between the coating and the substrate, with second critical load (Lc2) values greater than 100 N. Furthermore, they showed great toughness and wear resistance. These results show that this type of coating technique could be used in the most extreme applications and that they can compete with other techniques and coatings that to date they have not been able to compete with.

Previous studies have broadly dealt with TiAlSiN coatings that exhibit promising characteristics as surface protective layers for antiwear and antioxidation applications. In this regard, revealing the correlations among coating composition, structure, and properties is vitally important for developing advanced TiAlSiN coatings. The present work addresses the issue by studying the structure and properties of TiAlSiN coatings by tailoring Al/(Al + Ti) ratios. To this end, TiAlSiN coatings are produced by arc deposition with the Al/(Al + Ti) ratios of 0.31, 0.42, 0.51, and 0.62, respectively. The results show that, when the Al/(Al + Ti) ratio ranges from 0.31 to 0.51, the phase structure is mainly TiN phase, and the hardness, wear resistance and oxidation resistance of the films are increased with the rise in the Al/(Al + Ti) ratio. When the Al/(Al + Ti) ratio reaches 0.62, the oxidation resistance of the coating does not improve significantly, while the mechanical and wear properties of the coating are deceased due to the formation of w‐AlN phase. Therefore, the appropriate Al/(Al + Ti) ratio at 0.51 provides overall improvements including mechanical properties, and wear and oxidation resistances under operation conditions. These findings show that optimizing the Al/(Al + Ti) ratio is a promising way to develop TiAlSiN coatings with advanced structure and properties.
