“…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 XRD analysis of TiN(JCPDF#38-1420) coating, the 2θ 36.28 • (111) aspect and 42.59 • (200) aspect became stronger. These strong peaks indicate that the TiN coating mainly grows in the (111) and (200) directions [48], with improved crystalline structure [49]. TiN peaks are assigned following the face-centered cubic phase of TiN [17].…”

Titanium-based alloys have gained worldwide application over the past century. However, their low wear resistance remains an unresolved challenge for the Ti6Al4V alloy, which has significant industrial use. Therefore, it is an integral part in material selection and surface treatment in friction-wear applications. Tribological properties are not only material parameters but also system parameters where test conditions are essential. Hardness, roughness and contact conditions of coatings, which are especially important in surface treatments, affect wear modes. In this study, titanium nitride, titanium aluminum nitride and titanium carbon nitride coatings were obtained by unbalanced reactive magnetron sputtering to improve the weak tribological properties of Ti6Al4V alloy. The wear behavior was studied at room temperature in dry conditions. Wear tests were conducted under different loads and different sliding rates, which were followed by comparative analyses of their wear resistances. While the coated samples showed higher wear resistance than the uncoated Ti6Al4V alloy, the lowest wear track width was observed in TiN coating. Depending on the surface properties of the coatings, adhesion, abrasion and oxidation wear mechanisms were observed. It was concluded that a TiN coating could be a material of choice for applications where triple abrasive wear is dominant.

“…The surface properties and hardness had been improved by the TiN coating over SS316L steel surface which leads to higher performance in wear resistance when sliding against gamma irradiated Ti6Al4V counterpart [11]. An improved COF and Wear properties of arc deposited TiN coating has been found in severe sliding environments against Ti6Al4V [12].…”

Nitride coatings are generally used to enhance the surface property of the materials in order to perform wear and sliding environments to provide resistance against wear. Titanium Nitride coatings and Aluminium Chromium Nitride coatings were deposited as multilayer over the SS316L surface and the tribological studies were performed at high and room temperatures. The hardness of the multilayer coatings (TiN/AlCrN) provides 1000 VHN which is around five times higher than that of SS316L. The various wear mechanisms have been found from SEM morphology of worn surfaces for the different loading conditions at a high temperature of 400 °C. Chemical reactions led to the different wear mechanisms which were due to the thermal influence of the testing. Oxidation resistance was found for the elevated testing condition and the oxide formations were restricted with the elements of Ti, Cr, Fe, and Al, unlike room temperature testing.
