“…The TL is reported [106] to be formed and exist at all sliding conditions of load (10-50 N) and speed (0.5-4 m•s −1 ), with distinguishable microstructure as compared to the parent matrix material. Moreover, the thickness, composition, phases, and oxygen content of the TL varied at distinct sliding conditions with the counter-face.…”

“…Micro-structurally and tribo-behaviorally different layers were identified to have formed during dry sliding interaction of Ti64 with various counter-bodies. Li et al [106] reported that three distinct zones got , respectively. However, the size of the latter varied from being thick to thicker and then to be thin, with increment in velocity.…”

Tribology of Ti6Al4V: A review

2019

The deleterious innate attribute of Ti6Al4V, the workhorse material among the alloy series of titanium is its incompetent tribo-behavior. Infinite surface modification techniques, viz., the accretion of adherent appendage layers, diffusion hardening, infusion of residual stresses, microstructural evolution, and phase transformations were attempted to enhance the wear resistance of the alloy. The need lies to establish a bridge between the indigenous material properties and the tribo-characteristics of Ti6Al4V so that the enforced improvement techniques can raise the barriers of its applicability. A critical review of the microstructural transitions, mechanisms governing tribo-behavior and the parametric conditions leading to material removal at dry sliding conditions of Ti6Al4V, falls under the scope of this manuscript. Hence, the prime focus of the approach is to impart a clear-cut perception of the minute variations in mechanical, metallurgical, and tribological characteristics of the alloy at interactive instances with distinct counter-body surfaces.

Process-induced directional microstructure is identified as one of the key factors of anisotropic mechanical properties. This directional property significantly affects surface contact fatigue and corrosion of electron beam melting (EBM) built biomedical implants. In the current study, material removal on EBM built titanium (Ti6Al4V) subjected to reciprocating motion of commercially pure titanium spherical slider is investigated to identify the influence of the process-induced layered structure and environments on wear damage. Specimens developed by two different build orientations are mechanically stimulated using different sliding directions with nominally elastic normal load in dry, passivating, and synovial environments. It was noticed that EBM orientation significantly changes wear behavior in ambient environment. Wear resistance of mill-annealed Ti6Al4V was improved in passivating environment. Implications to improve useful life of orthopedic implants are discussed.

“…Some studies also showed that FC of TA19/WC-Co counterface is lower than that of both TC4/WC-Co and TC18/WC-Co counterfaces, indicating that the different types of titanium alloys have different tribological behaviors and wear mechanisms [14]. In fact, dry sliding friction behavior is mainly influenced by load, velocity, as well as the oxidation condition of the worn surface [15][16][17]. It is worth noting that surface roughness directly affects the friction behavior of the contact surfaces.…”

Abstract:The dry sliding friction and wear behaviors of TC11 titanium alloy subjected to the ultrasonic impacting and rolling process (UIRP) were studied in the present work. The microstructure of the deformation layer and the morphology of the worn surfaces were observed. The results clearly show that the wear performance of TC11 alloy after UIRP is better than that of TC11 alloy before UIRP under the same testing conditions. This can be attributed to the gradient nanostructure, work hardening, and low surface roughness of the treated surface layer. For the untreated samples, wear resistance first decreases and then increases with the increase of the sliding speed. Both the friction coefficient (FC) and wear rate reach a maximum value at a sliding speed of 478 r/min, and the corresponding worn surface is the most serious. While for UIRP treated samples, better friction and wear behaviors are obtained at a sliding speed of 478 r/min. This is because the deformation layer plays a protective role against wear.
