“…Nevertheless, in either system, a surface contact trace is observed due to the trace that the chip left during its displacement on the attack surface, leaving steel residues [44,45]. This contact trace is more visible in the uncoated burin, due to self-lubricant layer resulting from the HfN coating which improves its performance in wear processes, as previously reported [25][26][27][28][29][30]33,[39][40]. Similarly, Fig.…”

“…The literature presents that when processed as a thin films HfN hard coating has presented desirable properties for cutting tools such as: oxidation mitigation, high hardness in heat and better surface finish, which could generate a notorious improvement of the surface finish and increase of the useful life. Therefore, HfN-based coatings have been employed in ceramic and HSS cutting tools in machining of carbon steel workpieces [31][32][33][34]. Table 1 recompiles some reported mechanical properties between an uncoated HSS substrate and HfN sprayed coated HSS, which shows a significant hardness increase, which would increase tool lifetime during machining of metal part.…”

The industrial tool performance inspires the study of the machining of several materials with low production downtime. Aluminum is well-known for its high strength-to-weight ratio when compare both plastic and raft, thus making it advantageous for aerospace, construction and transport applications. However, aluminum machining damages the cutting tool with diverse wear mechanisms (adhesion, abrasion), thus suggesting a need for a new coating material. Previous studies show a high performance in abrasion resistance of Hafnium nitride [HfN] coated tools in turning of AISI1020 steel. This article evaluates the performance of [HfN] coated and uncoated burins (ASSAB 17) through roughing of Aluminum profiles by temperature sensing at the tool/material interface, workpiece roughness measurement and inspection of the cutting tool wear. Scanning electron microscopy and confocal microscopy were used to identify tool wear. A digital temperature sensing device displaying infrared long-wavelength was designed to examine the temperature due to its correlation on the tool wear. A significant improvement during aluminum roughing was observed with the use of [HfN] coatings, due to increase of the wear resistance of the ASSAB 17 burin, thus improving the surface finish.

“…Because of their minimum work function, HfN films are highly favorable as an emitter material in field emitter arrays. [ 254,256 ] Besides their excellent mechanical, electrical, and optical properties, HfN films find their applications in the areas of hard coatings, [ 257,258 ] cutting tools, [ 255,259 ] diffusion barriers, [ 260 ] microelectronics, [ 261–263 ] optical field, [ 264 ] solar energy, [ 265,266 ] crucibles, [ 253,267 ] etc.…”

Transition metal nitride (TMN) thin films exhibit outstanding physical, chemical, and mechanical properties, making them best suitable for a wide variety of applications. The most commonly used technique to produce metal nitride thin films with specific properties at optimum conditions is magnetron sputtering. Considering this, this review begins with advancements in the sputtering process from basic diode sputtering to the most commonly used pulsed magnetron sputtering. Further, the literature on several TMNs deposited via magnetron sputtering is summarized, referring to several articles that have been published during the last decades. The main emphasis lies on nitride-based thin films' structural, morphological, and mechanical aspects for various applications. In addition, the influence of reactive gas flow rate, substrate temperature, layer thickness, postannealing temperature, substrate bias voltage, protective layers, the sputtering technique adopted, etc. on the quality and performance of the thin films is also focused. The overall review work can be beneficial for the students and researchers in understanding the basic sputtering phenomenon with its advancements, the relationship between deposition parameters and surface properties, and to know the current research trend for exploring several research gaps in the literature.
