“…Considering the need to develop coatings with increased wear and corrosion resistance, ternary compounds, such as titanium niobium nitride (TiNbN), combine the properties mentioned above. These coatings provide better adhesion at the film/substrate interface, increased thermal stability and wear resistance, enabling them to reach high operating temperatures [ 21 , 22 , 23 ].…”

This study focused on investigating the adhesion and tribological properties of niobium-doped titanium nitride (TiNbN) coatings deposited on D2 steel substrates at various substrate temperatures (Ts) under simulated cutting conditions. X-ray diffraction confirmed the presence of coatings with an FCC crystalline structure, where Nb substitutes Ti atoms in the TiN lattice. With increasing Ts, the lattice parameter decreased, and the crystallite material transitioned from flat-like to spherical shapes. Nanoindentation tests revealed an increase in hardness (H) with Ts, while a decrease in the elastic modulus (E) resulted in an improved elastic strain limit for failure (H/E) and plastic deformation resistance (H3/E2), thereby enhancing stiffness and contact elasticity. Adhesion analysis showed critical loads of ~50 N at Ts of 200 and 400 °C, and ~38 N at Ts of 600 °C. Cohesive failures were associated with lateral cracking, while adhesive failures were attributed to chipping spallation. The tribological behavior was evaluated using a pin-on-disk test, which indicated an increase in friction coefficients with Ts, although they remained lower than those of the substrate. Friction and wear were influenced by the surface morphology, facilitating the formation of abrasive particles. However, the absence of coating detachment in the wear tracks suggested that the films were capable of withstanding the load and wear.

“…Among the most commonly used coatings in the industry are Titanium Nitride (TiN) and Niobium Nitride (NbN). In the present work, D2 steel samples with different heat treatments and steels with Titanium Niobium Nitride (TiNbNx) coatings were used, which are employed for industrial applications as a cutting tool [ 13 , 14 , 15 ].…”

Automatic Method for Vickers Hardness Estimation by Image Processing

et al. 2022

Hardness is one of the most important mechanical properties of materials, since it is used to estimate their quality and to determine their suitability for a particular application. One method of determining quality is the Vickers hardness test, in which the resistance to plastic deformation at the surface of the material is measured after applying force with an indenter. The hardness is measured from the sample image, which is a tedious, time-consuming, and prone to human error procedure. Therefore, in this work, a new automatic method based on image processing techniques is proposed, allowing for obtaining results quickly and more accurately even with high irregularities in the indentation mark. For the development and validation of the method, a set of microscopy images of samples indented with applied forces of 5N and 10N on AISI D2 steel with and without quenching, tempering heat treatment and samples coated with titanium niobium nitride (TiNbN) was used. The proposed method was implemented as a plugin of the ImageJ program, allowing for obtaining reproducible Vickers hardness results in an average time of 2.05 seconds with an accuracy of 98.3% and a maximum error of 4.5% with respect to the values obtained manually, used as a golden standard.

“…Surface engineering combines several methods. This is a directional change in the physico-chemical properties of the surface layers of materials by deforming [5], modifying [6], applying single-layer [7], multiperiod [8,9], multielement [10] coatings and protective layers. Also various combined methods are used [11].…”

To determine the patterns of structural engineering of vacuum-arc coatings based on niobium nitride in the NbN/Cu multilayer composition, the effect of layer thickness and bias potential on the structural-phase state and physico-mechanical characteristics of vacuum-arc coatings was studied. It was found that the metastable δ-NbN phase (cubic crystal lattice, structural type NaCl) is formed in thin layers (about 8 nm thick) regardless of Ub. With a greater thickness of the layers of niobium nitride (in the multilayer NbN/Cu composition), the phase composition changes from metastable δ-NbN to the equilibrium ε-NbN phase with a hexagonal crystal lattice. An increase in the bias potential during deposition from -50 to -200 V mainly affects the change in the preferential orientation of crystallite growth. The highest hardness (28.2 GРa) and adhesive resistance is achieved in coatings obtained at Ub = -200 V with the smallest layer thickness. The highest hardness corresponds to the structurally deformed state in which the crystallite texture is formed with the [100] axis perpendicular to the growth surface, as well as a large microstrain (1.5%) in crystallites.
