“…Compared to the Ti-6Al-4V alloy produced by traditional forging, the SLM/EBM-fabricated materials show a unique microstructure and properties [ 17 , 18 , 19 , 20 , 21 ]. The wear property of Ti-based alloys is one of the most important properties to be considered for particular applications [ 22 , 23 , 24 , 25 , 26 ]. The wear properties are not, however, extensively studied and compared.…”

The wear properties of Ti-6Al-4V alloy have drawn great attention in both aerospace and biomedical fields. The present study examines the wear properties of Ti-6Al-4V alloy as prepared by selective laser melting (SLM), electron beam melting (EBM) and conventional forging processes. The SLM and EBM samples show better wear resistance than the forged sample, which correlates to their higher hardness values and weak delamination tendencies. The EBM sample shows a lower wear rate than the SLM sample because of the formation of multiple horizontal cracks in the SLM sample, which results in heavier delamination. The results suggest that additive manufacturing processes offer significantly wear-resistant Ti-6Al-4V specimens in comparison to their counterparts produced by forging.

“…In the past decades, binary Li et al, 2018), ternary (Yao et al, 2015; and quaternary Wang et al, 2017) transition metal nitride or carbide coatings have been well explored and applied in many industrial and engineering fields. These coatings possess very high hardness, but their brittle property has impeded its application in certain areas, such as automotive parts, mold, tools etc.…”

An equiatomic CoCrFeMnNi high-entropy alloy (HEA) thin film coating has been successfully developed by high-vacuum Radio Frequency (RF) magnetron sputtering. The deposition of a smooth and homogenous thin film with uniformly distributed equiaxed nanograins (grain size ∼ 10 nm) was achieved through this technique. The thin film coating exhibits a high hardness of 6.8 ± 0.6 GPa, which is superior compared to its bulk counterpart owing to its nanocrystalline structure. Furthermore, it also shows good ductility through nanoindentation, which demonstrates its potential to serve as an alternative to traditional transition metal nitride or carbide coatings for applications in micro-fabrication and advanced coating technologies.

“…Ref. [7] also reported that the TiSi(12 at.%)CN coatings presented the highest hardness of 4100 HV as compared with TiSi(6 at.%~8 at.%)N coating (3700 HV), and the oxidation stability temperature for the TiSi(4 at.%)CN coating also upped to 900 °C. In addition, the influence of carbon content (6.9 -22.2 at.%) on microstructure and mechanical property also was discussed [6], the nanocrystallite of TiN, TiC and Ti(C, N) was formed in TiSiCN coating as well as a-Si3N4, a-SiC and little a-C, the maximum hardness of 39.8 GPa was obtained for TiSiCN coating at a carbon content of 11.9 at.%.…”

TiSiCN coatings were prepared using DC and RF magnetron co-sputtering system. The influence of target powers on phase structures, mechanical properties, tribological and electrochemical properties were studied. The results indicated the coatings presented an amorphous structure, and the highest microhardness of 1566.4 HV was obtained at a target power of 200 W. In terms of the electrochemical properties in coolant, the higher charge transfer resistance of 2.64 × 10 7 Ωcm 2 and the polarization resistance (~1.10 × 10 8 kΩ.cm 2) were obtained at low target power, indicating a better corrosion resistance. Furthermore, the friction coefficient was 1.01 ~ 1.14 as sliding against SUS440C balls in air. In contrast, the friction coefficient decreased to 0.45 ~ 0.58 in coolant, and the wear mechanism changed from oxidation wear into abrasive wear.
