In this work, the Liquid Impingement Erosion (LIE) performances of deep-rolling (DR) treated and non-treated Ti64 were investigated. Various erosion stages, from the incubation to the terminal erosion stages, could be observed. A full factorial design of experiments was used to study the effect of DR process parameters (Feed Rate, Spindle Velocity, Number of Passes, Pressure) on the residual st...

3D printed porous titanium (Ti) holds enormous potential for load-bearing orthopedic applications. Although the 3D printing technique has good control over the macro-sturctures of porous Ti, the surface properties that affect tissue response are beyond its control, adding the need for tailored surface treatment to improve its osseointegration capacity. Here, the one step microarc oxidation (MAO...

PURPOSE The aim of the present paper was a question of structural identification and evaluation of strength parameters of Titanium (Ticp - grade 2) and its alloy (Ti6Al4V) which are used to serve as a base for those permanent prosthetic supplements which are later manufactured employing CAD/CAM systems. METHODS Microstructural tests of Ticp and Ti6Al4V were conducted using an optical microsco...

Because of the risk of galvanic corrosion, combination use of different metals is supposed to be prohibited in in-vivo environment. Ti-6Al-4V (Ti64) has been use for biomaterials due to its good biocompatibility [1-3]. Therefore, the combination use with the conventional stainless steel of SUS316L (SUS) is increasing due to accidental misuse in emergency cases or necessary choice of stainless w...

Abstract Directed energy deposition (DED) was used to produce niobium carbide (NbC)‐reinforced Ti6Al4V (Ti64) metal–matrix‐composite (MMC) structures. The objective improve upon Ti64's wear and oxidation resistance. characterization techniques consisted of scanning electron microscopy (SEM), backscattered (BSE) imaging, energy‐dispersive X‐ray spectroscopy (EDS), diffraction analysis (XRD), the...

Titanium alloys exhibit high specific strength and stiffness that fit structural applications demanding lightweight. The microstructure of the alpha-beta titanium alloys can be changed by thermomechanical processes such as heat treatments and pre-forging to achieve a certain ductility. Ceramic reinforcements can improve specific strength and stiffness, and also the wear resistance. In Situ part...

Gradient structure metals have good comprehensive properties of strength and toughness are expected to improve the dynamic mechanical materials. However, there few studies on gradient structured materials, especially titanium alloys. Therefore, in this study, ultrasonic surface rolling is used prepare a layer Ti-6Al-4V, quasi-static compressive coarse-grained Ti-6Al-4V (CG Ti64) gradient-struct...
