In this study, the performance against erosive wear of PVD TiN (titanium nitride) coating was evaluated using an erosion test rig similar to that described in the standard ASTM G76-95. This coating normally has various industrial applications such as tapping, drilling, dry machining and punching. Angular silicon carbide (SiC) was used as an abrasive particle with a grain size of 350 -450 µm. Erosion tests were carried out using different incident angles, 30˚, 45˚, 60˚ and 90˚ with a particle velocity of 24 ± 2 m/s, an abrasive flow rate of 0.7 ± 0.5 g/min, and the test temperature was between 35˚C and 40˚C. The particle velocity and the abrasive flow rate were low in all of the tests to reduce the interaction between the incident and the rebounding particles in the system. The surfaces were examined with a scanning electron microscope (SEM) to characterize the erosive damage. The wear mechanisms identified were brittle fracture characterized by radial cracks on the surface by multiple impact and a few pits at 30˚, while a few cracks and the formation of craters in random positions were observed at angles near or at 90˚. Elliptical scars were observed at 30˚ and 45˚, which are a characteristic feature when the specimens are impacted at low-incident angles (α ≤ 45˚) whereas a roughly circular scar was seen at 60˚ and 90˚. In addition, roughness variations were analyzed using atomic force microscopy (AFM), before and after the erosion tests, and the results exhibited an increase in the roughness as the TiN samples were impacted at angles near or at 90˚.

“…This means that instead of the coating toughness, the ratio H 3 /E ⁎2 should be used to assess the protective efficiency of the thin film exposed to the external load. The H 3 /E ⁎2 of the coating seemed to play an important role with respect to its erosion wear during abrasive test [48,49]. Coatings with high H 3 /E ⁎2 could exhibit lower erosion rates.…”

High temperature composite target AlN-TiB 2 -TiSi 2 with heterogeneous distribution of compounds (AlN-50 wt.%; TiB 2 -35 wt.%; TiSi 2 -15 wt.%) is used for sputtering via combined reactive/non-reactive DC magnetron sputtering onto substrate materials either cylindrical polished steel (Fe, 18%-Ni, 12%-Cr, 10%-Ti) 3 mm diameter or monocrystalline silicon. The gradient coating has been produced by sequential non-reactive and reactive sputtering of the target. The structural and morphological properties of the deposited films are analyzed by transmission electron microscopy, scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy and Raman spectroscopy. The tribo-mechanical properties are studied by means of nanoindentation and nanowear tests. The gradient film is composed of two layers with different microstructure and elemental composition. The first layer with thickness~200 nm is mainly based on light B, C and N as well metal elements Al, Si and Ti. The presence of very well distributed nanocrystals embedded in an amorphous matrix, with crystal sizes ranging from 5 to 40 nm is observed in the second layer~700 nm thickness and composed of Al, Ti, Si, B, and N. Films show very flat surfaces, with roughness around 0.35 nm. The hardness, elastic modulus, elastic recovery (W e ), H/E ⁎ ratio and H 3 /E ⁎2 ratio are determined as 17.55 GPa, 216.7 GPa, 60%, 0.08 and 0.12 GPa, respectively. Nanowear tests demonstrate relatively high wear resistance of the coatings. Samples show promising characteristics for hard protective adaptive coatings and diffusion barriers due to short propagation of dislocations in the amorphous matrix and the elastic and hard nature of the nanocomposite structure.

“…Consequently, alloyed and nanocomposite TiN-based coatings have also been investigated. A system that is now being implemented industrially is TiAlN which has been shown to not only possess high SPE resistance [92,97] but also good stability at higher temperature [132][133][134]. In this category, TiCN has also shown much promise [86,95,99].…”

“…However, they are difficult to implement in practice since they need to be deposited at temperatures that exceed the permissible limits of the metallic components. For that reason, the most frequently used coatings for SPE protection are TiN-based in monolithic [85,87,89,91,92] or multilayer [90,105,106] forms, which can be deposited on technologically relevant substrates.…”
