“…Indeed, high Hardness to Young's modulus ratio of ceramic coatings implies improved wear resistance. Also, wear mechanism in these coatings is abrasive wear due to the nature of ceramic coatings (with little plastic flowability and high probability fracture) and properties of the used pin which accelerates abrasive wear conditions [17,39]. This may be confirmed by continuous grooves throughout the wear track in SEM micrographs (Fig.…”

“…Released particles could fill the pores between SiC abrasive particles over the counterpart. As a result, contact area between the specimen and counterpart increases which in turn leads to higher friction coefficient value [39,40]. When the coating is totally removed, the substrate would be exposed to abrasion which is why friction coefficient became approximately constant.…”

“…The sliding wear mechanism of Ti-6Al-4V alloy is complex because it has a complex microstructure feature. The complexity of wear mechanism of such alloy is due to the oxide layer that formed during testing, adhered, and then transformed to the counterface surface [15,25]. This is obvious in Fig.…”

“…The tribological properties of α and α+β titanium alloys have been investigated extensively by many researchers [13,14]. These Ti-alloys are insufficient in tribological performances because they are characterized by high coefficients of friction, severe adhesive wear with a high tendency to seizing and low abrasion resistance, when they slide against other engineering materials [15]. It is known that titanium alloys have poor wear resistance due to their low work hardening coefficient, low shear strength, and limited protection offered by their thin and brittle surface oxides [16,17].…”

The mild to severe wear transition of Ti-6Al-4V titanium alloy was investigated. The correlation between microstructure and wear micro-mechanisms was also studied. Hot swaging at 900 °C was performed on the as-cast samples and thereafter two different solution treatments were applied on the swaged samples. The first treatment was applied at a temperature of 850 °C (below the β-transus temperature) for getting a bimodal structure (α+β), while the second treatment at 1050 °C was applied (above the β-transus) for getting lamellar structure (β). The solution treated lamellar structure resulted in ultimate strength of 1335 MPa and a hardness of 440 HV20 which are significantly superior to the bimodal structure. Wear behaviour of the studied Ti64 alloy was investigated at different sliding speeds in the range of 0.5 to 2.5 m/s with an interval of 0.5 m/s. The mild to severe wear transition was obtained at 1.5 m/s. The lowest wear rate was reported for the samples solution treated at 1050 °C due to their fine lamellae structure with high hardness. The worn surfaces of some selected samples were examined using SEM to determine the wear micro-mechanisms.

“…The maximum impact force is often used as a test control condition adopted by most studies on impact wear behavior [6][7][8][9][10][11]. Knotek [6] developed a repetitive impact test in which a ceramic ball could be made to impact the surface of materials at different cycles and with different magnitudes of impact force.…”

An energy-controlled cycling impact test was applied to evaluate the impact wear behavior of hard coating. A multilayer TiN/Ti coating with a total thickness of ~10 μm, containing two TiN layers and two Ti layers, with the thickness ratio of these two kinds of the layers being 9:1, was chosen as the research object. The impact velocities were 60, 120, and 180 mm/s, and the impact cycles were 10, 102, 103, and 104, respectively. Damage morphology observation and numerical simulation were used to analyze the failure mechanisms. The results show that the contact time keeps almost constant under different impact velocities and cycles. Impact peak forces remain unchanged with increasing cycles at the same velocity, but they increase linearly with impact velocities, reaching a maximum value of 262.26 N at 180 mm/s. The energy dissipated rate (EDR) increases from 31.58% at 60 mm/s to 35.59% at 180 mm/s, indicating the degenerative toughness. Two impact-wear failure mechanisms are found in impact zones of the coating; these are peeling and circular cracks. Peelings are induced by cycling high-stress gradients in hard layers and interfaces. Circular cracks are caused by cycling tensile stresses in the form of fatigue at the edge of impacted pits.
