“…However, the poor wear resistance extensively limits their further applications [5,6]. Among various surface treatments, boriding is a kind of thermo-chemical treatment which can generate a hard borided layer on the surface of titanium alloys.…”

In this paper, a nanocrystalline surface layer without impurities was fabricated on Ti-6Al-4V alloy by means of surface mechanical attrition treatment (SMAT). The grain size in the nanocrystalline layer is about 10 nm and grain morphology displays a random crystallographic orientation distribution. Subsequently, the low-temperature boriding behaviors (at 600 °C) of the SMAT sample, including the phase composition, microstructure, micro-hardness, and brittleness, were investigated in comparison with those of coarse-grained sample borided at 1100 °C. The results showed that the boriding kinetics could be significantly enhanced by SMAT, resulting in the formation of a nano-structured boride layers on Ti-6Al-4V alloy at lower temperature. Compared to the coarse-grained boriding sample, the SMAT boriding sample exhibits a similar hardness value, but improved surface toughness. The satisfactory surface toughness may be attributed to the boriding treatment that was carried out at lower temperature.

“…The high degree of hardness achieved (exceeding even 50 GPa [43,44]) is given by the interfaces between layers, acting as energy barriers that counteract the motion of dislocations [45,46]. Several nanolayered superlattice hard coatings have already been tested in recent years, including TiN/NbN, TiAlN/CrAlN, and CrN/NbN, as an environmentally friendly replacement for hard chromium [47][48][49][50][51][52][53][54][55][56][57][58][59][60]; moreover, these have shown good wear resistance [61].The evolution of conventional hard coatings for cutting tool applications has been intensively investigated [62] and the market's requests to increase productivity and sustainability (i.e., through the reduction of lubricants) of the machining processes, together with reduced costs and lead time [63], suggest the need to fully exploit the potential of advanced hard coatings, which are already available, in order to evaluate their potential use for cutting tool applications. Therefore, the aim of the present paper is to investigate the dry sliding wear performance of two commercially available coatings-a multilayer AlTiCrN and a superlattice (nanolayered) CrN/NbN deposited on a S600 high speed steel.…”

Thin hard coatings are widely known as key elements in many industrial fields, from equipment for metal machining to dental implants and orthopedic prosthesis. When it comes to machining and cutting tools, thin hard coatings are crucial for decreasing the coefficient of friction (COF) and for protecting tools against oxidation. The aim of this work was to evaluate the tribological performance of two commercially available thin hard coatings deposited by physical vapor deposition (PVD) on a high speed tool steel (S600) under extreme working conditions. For this purpose, pin-on-disc wear tests were carried out either at room temperature (293 K) or at high temperature (873 K) against alumina (Al2O3) balls. Two thin hard nitrogen-rich coatings were considered: a multilayer AlTiCrN and a superlattice (nanolayered) CrN/NbN. The surface and microstructure characterization were performed by optical profilometry, field-emission gun scanning electron microscopy (FEGSEM), and energy dispersive spectroscopy (EDS).

“…In addition to these studies, there are several other available studies in the literature targeting TiN coatings along with their processing techniques and analyses [29][30][31][32][33][34][35][36]. In addition to TiN coating, different types of hard coatings developed under various employed conditions have also been published extensively [37][38][39][40][41][42][43][44][45][46][47][48]. The basic idea discussed in those studies is related to the properties and characteristic of deposited coatings, which are subjected mainly to the change of process parameters, type of material and processing approach.…”
