“…The tribofilm formed on the contact interface consists of the Magneli-phase intermediate titanium oxides, as well as TiO 2 . As reported in [ 19 , 20 ], these intermediate oxides TiOx for 1 < x < 2 elasto-plastically deform as a lubricious oxide to form a thin tribofilm. The thin tribofilm grows radially from the center line of the contact interface in Figure 4 , Figure 5 and Figure 8 a; this trace proves this lubricious elasto-plastic flow of intermediate titanium oxide films.…”

Dense β-SiC coating with 3C-structure was utilized as a dry cold forging punch and core-die. Pure titanium T328H wires of industrial grade II were employed as a work material. No adhesion or galling of metallic titanium was detected on the contact interface between this β-SiC die and titanium work, even after this continuous forging process, up to a reduction in thickness by 70%. SEM (Scanning Electron Microscopy) and EDX (Electron Dispersive X-ray spectroscopy) were utilized to analyze this contact interface. A very thin titanium oxide layer was in situ formed in the radial direction from the center of the contact interface. Isolated carbon from β-SiC agglomerated and distributed in dots at the center of the initial contact interface. Raman spectroscopy was utilized, yielding the discovery that this carbon is unbound as a free carbon or not bound in SiC or TiC and that intermediate titanium oxides are formed with TiO2 as a tribofilm.

“…Aizawa et al [20] claimed that no structural change was seen after Cl-implantation which means that chlorine atoms must be present as interstitial atoms into the TiN lattice.…”

“…The role of chlorine ion in this type of applications was never investigated. However, it is known that when implanted on TiN coatings in cutting tools and forming dies, this ion gives rise to a significant decrease of friction and wear in dry conditions, which was attributed to a mechanism of self-lubrication [20,21].…”

“…In recent studies, the implantation of nitrogen [7][8][9][10], carbon [11][12][13], chlorine [14][15][16], and several other kinds of metallic elements [7] into TiN films has been carried out to improve tribological properties. These studies concluded that both friction coefficients and wear were significantly reduced upon the implantation of chlorine because it oxidized a shallow surface region of the TiN film and formed an elasto-plasticity deformed Magneli phase [14][15][16]. In addition, since chlorine compounds have been commonly used as EP additives to reduce friction and wear, the implantation of chlorine results in the formation of films that have a lubricating performance similar to tribofilms.…”

Phosphorous (P) ion implantation was performed on a steel substrate to investigate the effect of the P implantation on the friction characteristics of steel lubricated with oil. To determine the characteristics of the P-implanted layer, several kinds of surface analyses were carried out, resulting in a correlation between the X-ray photoelectron spectroscopy depth profile and the thickness from spectroscopic ellipsometer. A three balls-on-disc tribometer was employed with sliding speeds ranging from 3 mm/s to 40 cm/s. The friction coefficient of the P-implanted steel was relatively lower at speeds below 10−1 m/s, compared with the unimplanted steel. This could account for both the sacrificing nature and the adhesion behaviour of the P-implanted layer.
