“…Furthermore, this oxygen-rich tribomaterial was subsequently deformed by the contact pressure, fragmented and finally detached to form the wear particles (Figure 7c). Thus, fatigue produced crack nucleation and propagation, generating new debris (Figure 7c), some of which mechanically mixed by the action of shear and compressive stresses to form the tribolayer while others were hardened and became a large abrasive, producing the groves in the center of the wear track (Figure 7a) [14].…”

This work aims to study the effect of the counterpart materials (100Cr6, Al2O3 and WC-Co) on the tribological properties of TiAlN thin films deposited on AISI H13 steel substrate by reactive magnetron co-sputtering. The structural characterization of the TiAlN films, performed by X-ray diffraction, showed (220) textured fcc crystalline structure. The values of hardness and elastic modulus obtained by nanoindentation were 27 GPa and 420 GPa, respectively, which resulted in films with a relatively high resistance to plastic deformation. Ball-on-disk sliding tests were performed using normal loads of 1 N and 3 N, and 0.10 m/s of tangential velocity. The wear coefficient of the films was determined by measuring the worn area using profilometry every 1000 cycles. The mechanical properties and the chemical stability of the counterpart material, debris formation and the contact stress influences the friction and the wear behavior of the studied tribosystems. Increasing the hardness of the counterpart decreases the coefficient of friction (COF) due to lower counterpart material transference and tribofilm formation, which is able to support the contact pressure. High shear stress concentration at the coating/substrate interface was reported for higher load promoting failure of the film-substrate system for all tribopairs.

“…The aluminum is frequently used to form titanium-aluminum nitride (Ti-Al)N [9]- [12]. (Ti-Al)N thin films deposited by PVD have high hardness at elevated temperatures ( 800 o C) and improved performance in cutting operations at higher velocities compared to TiN [13], [14].…”

“…The results showed that the AlCrN coating exhibited higher hardness, but lower wear resistance as compared to the CrN coating. The AlCrN coating formed by CrN alloying with aluminum would show significantly improvement in high temperature oxidation resistance but not necessarily in wear resistance under the condition of ambient temperature [4] .…”

Thin hard coatings provide the much needed protection for steel thixoforming tools that must resist wear at high temperatures. The wear resistance of AlTiN-and AlTiON-coated hot work tool steel was investigated at 1023 K (750°C), measured to be the cavity surface temperature shortly after the steel slurry was forced into the thixoforming die. The wear tests were repeated in exactly the same fashion with uncoated tool steel samples to identify the impact of AlTiN and AlTiON coatings on the high-temperature wear performance of X32CrMoV33 tool steel. The nature, the thickness, and the adherence of the oxide scales impact the tribological behavior. The poor adherence and limited ductility of ferrous oxides promote the failure of the oxide scale impairing the resistance to wear of the hot work tool steel at elevated temperatures. The substantial softening in the X32CrMoV33 hot work tool steel is also critical in the wear volume loss it suffers. AlTiN and AlTiON coatings, on the other hand, form a stable and protective oxide surface layer at high temperatures and therefore provide an enhanced resistance to oxidation. The latter is relatively more resistant to oxidation and is thus the better of the two coatings tested in the present work.
