“…What happens usually is simultaneous occurrence of several different failure modes which makes the result of the test difficult to interpret. The coating-substrate duo behaves as a single mechanical system that faces to deformations created by external loads under service conditions [28], in scratch test, the action of diamond stylus. By concerning this point, mechanical failure of the duo can be originated from one or both of these two factors: (i) Cohesive failure (failures in the coatings or in the substrate) which occurs by tensile stress behind the stylus.…”

“…However, these coatings decline due to the absence of adhesion to the tool substrate which leads to early wear, reducing its cutting performance. 2 , 3 A suitable adhesion is important for the tool substrate because during service the surface coatings have to experience higher mechanical and thermal loads. 4 In general, numerous methods were used to enhance adhesion.…”

Titanium nitride coatings are extensively adopted as an intermediate adhesion layer in the cutting tools because of its superior mechanical properties. The interdependence of each process parameter during the deposition of such a coating process is nonlinear, and hence, it becomes a challenge to determine the output responses without carrying out a wide range of experiments. So to minimize the experiments, Taguchi-based L9 design of experiments were employed in this study with three factors and three levels such as Argon (Ar): Nitrogen (N2) gas mixture, Pulsed direct current power, and deposition time for depositing titanium nitride thin films on silicon (100) and tungsten carbide substrates using Pulsed direct current magnetron sputtering technique, where conventional direct current magnetron sputtering cannot be deployed using titanium nitride target. Multiple output responses such as average thickness, surface roughness, nano-hardness, Young’s modulus, wear track deformation, and coefficient of friction were measured by carrying out the systematic investigations, and a single optimum solution was obtained using Grey relational analysis. From the Grey relational analysis, the optimum Ar:N2 gas flow mixture, Pulsed direct current power, and deposition time for improved titanium nitride adhesion layer are 300 W, 10:5 sccm, and 5 min, respectively. Further, grazing incidence x-ray diffractometer profiles of deposited films exhibits (111) and (200) reflections corresponding to the titanium nitride phase, and the morphological analysis also revealed the existence of strongly faceted nano-grains with a triangular-shaped morphology.

“…Therefore, the study of wear and control mechanisms is crucial to increasing process efficiency. Due to the low melting point, diffusive wear, and superficial plastic deformation wear, mechanisms are difficult to find in the tool after machining aluminum, with the main wear mechanisms being abrasion and adhesion [7][8][9]. Abrasion is supposed to be produced by hard particles from the precipitates or particles from the cutting tool [10], while the adhesion mechanism is caused by the interaction between tool and workpiece, which produces a high contact pressure that facilitates the transfer of particles from one surface to another [11].…”

Light alloy machining is a widely implemented process that is usually used in the presence of cutting fluids to reduce wear and increase tool life. The use of coolants during machining presents negative environmental impacts, which has increased interest in reducing and even eliminating their use. In order to obtain ecofriendly machining processes, it will be necessary to suppress the use of cutting fluids, in a trend called “dry machining”. This fact forces machines to work under aggressive cutting conditions, producing adhesion wear that affects the integrity of the parts’ surfaces. This study describes cutting tool wear mechanisms in machining of UNS A92024 samples under dry cutting conditions. Energy dispersive spectroscopy (EDS) analysis shows the different compositions of the adhered layers. Roughness is also positively affected by the change of the cutting geometry produced in the tool.
