“…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.

“…Guzman et al [56] in 2016 had carried out an experiment in pursue of studying the effectiveness of single layer hafnium nitrite as a thin protective coating applied onto cutting tools. The deposition was by a radio frequency magnetron sputtering physical vapor deposition, and it was 52% ionic-covalent hafnium nitrite thin protective coating This brings the great thermal, great hardness, and high melting point properties, and electrical conductivity of the thin protective coating.…”

Earning trust among high strength material industrialists for its sophistication, thin protective coating has gained its own maturity to date. As a result of active development in the industries, working tool has the capability of fabricating high strength materials with remarkable durability. For example, unwanted tool wear due to thermally softening problems can be avoided. Therefore, the solution for that is protecting the tool with a thin protective coating that can be coated by various coating deposition methods. With the thin protective coating itself possessing remarkable degree of chemical and mechanical properties, the combination of both makes the thin protective coating lead to a useful extend. This paper provides a review of various research activities and various developments in the wear prone industries. Researchers have explored a number of thin protective coatings for the last century to provide a valuable guide for a most practical option. With the state of the art development of the coating methods such as electrodepositing, radio frequency ion source implantation, electron beam implantation, plasma-sprayed coating deposition, flame-sprayed coating deposition, chemical catalytic reduction deposition, vacuum-diffused deposition, vapor deposition, chemical vapor deposition, physical vapor deposition, plasma arc deposition, and some others, this paper presents the continuous development on the enhancement of the capability of the working tool chronologically since the last century. Such development was studied in connection with the ability to outlast the performance of working tool, which elevates expectations that thin protective coatings are no longer extended far beyond.
