“…However, WR has the opposite effect because the greater the friction distance, it provides relief to the surface to slide. This result was also obtained in another study that the WR strictly raised until it reached 1700 m [17]. The authors found that thermo-mechanical effects determine how Ti6Al4V wears, and they pointed out that a tribo-oxide layer made of titanium and vanadium oxides forms on the surface of the sample.…”

The need for titanium and its alloys has led to a significant increase in commercial manufacturing, although this material’s poor tribological qualities have been a drawback. The present study was to determine the effect of laser-textured surfaces to enhance Ti6Al4V surface wear performance. The sample underwent laser texturing based on pre-set parameter values at 15 W power at a laser scanning speed of 200 mm/s with a frequency of 50 kHz. The surface morphological and topological profile of laser-textured Ti6Al4V was characterized with also the surface microhardness. A comparative appraisal of wear rate (WR) and coefficient of friction (COF) for related samples of as-received Ti6Al4V and laser-textured Ti6Al4V was performed under dry and oil sliding conditions. The results revealed that the formation of oxidation due to the frictional force and plastic displacement plays a role of abrasive to the laser-textured surface and may result in increasing the COF. The wear rate of the laser-textured surface of Ti6Al4V exhibited 88.31% improvement compared to the as-received Ti6Al4V in the dry sliding wear test. It was proved that Ti6Al4V could benefit from LST to gain effectively enhanced wear performance.

“…The principal wear processes in the aforementioned three phases are delamination wear mechanism, abrasion wear mechanism and oxidation wear mechanism at low, medium, and high sliding speeds, respectively. The primary types of wear in Ti-6Al-4V alloy at 25-200 • C includes abrasion, delamination, and adhesion wear (13) . Depending on the manufacturing methods utilized, the microstructure of a metallic material can vary greatly, which can result in a wide range of mechanical and its material characteristics as well as varying wear resistance (14) .…”

Objectives: To evaluate the tribological and corrosive characteristics of an additively printed gyroid Ti-6Al-4V for Bio medical implant application. Methods: Direct Metal Laser Sintering with regulated input process parameters were used to print the samples. Corrosion investigations have been completely investigated using Potentiodynamic polarization under simulated body fluid conditions. The wear parameters for the samples were maintained with normal load ranging from 10 to 50 N, with sliding velocity ranging from 0.5 to 1.5 m/s for a sliding distance of 1000 m. The further study investigates the impact of load and velocity on the coefficient of friction (COF) and wear rate of the Gyroid samples. Findings: According to the results obtained, the material with the highest resistance to corrosion is exhibited by gyroid lattice Ti-6Al-4V that has a porosity of 60%. These samples exhibited by a worn-out rate of 2 x 10-11 m 3 /m and 5.3 x 10-11 m 3 /m for the normal load of 10 N and 50 N respectively. Minimum wear rate of 3.3 x 10-11 m 3 /m was obtained for a sliding velocity of 0.5 m/s, where a maximum wear rate was obtained at 1.5 m/s of 3.7 x 10-11 m 3 /m. Sample C has better tribological properties and is shown good wear resistance, when compared to sample A & B, which is attributed to the highest micro hardness of sample C of 467 HV. Novelty: The work presented in this study exhibits a unique approach by fabricating a gyroid lattice structure with varying levels of porosity. The limited availability of literature on tribological and corrosion issues necessitates the identification of a unique research need. An investigation of the effect of wear mechanisms on the tribological features of Gyroid Ti-6Al-4V is considered to be a unique research attempt.
