“…e Ti-6Al-4V alloy stands out among these alloys because of its high strength-to-weight ratio, corrosion resistance, and low density [10]. Ti and Ti alloys are lightweight and have improved biocompatibility and corrosion resistance, making them popular in medical and dental applications [11]. Protecting Ti-6Al-4V substrates with PVD coatings has been shown to improve mechanical characteristics, biocompatibility, osseointegration, wear, and corrosion resistance [12].…”

In this study, the wear behavior of a physical vapor deposition (PVD) AlTiN coated on the titanium alloy was investigated. Response surface methodology (RSM) was used to analyze input factors, such as load (A), sliding speed (B), and sliding distance (C), while wear mass loss (WML) and coefficient of driction (COF) were considered as the response parameters. The statistical analysis shows that main factors, that is, interaction of AC and pure quadratic terms B2 and C2, have maximum influences on WML. However, COF was highly affected by load, sliding speed, and interaction of AB and quadratic term A2. The present work attempts to carry out empirical modeling to predict output response on WML and COF. Desirability-based optimization technique was employed to obtain minimum WML and COF. Microscopy images of the wear tracks reveal visible grooves and scratches that confirm abrasive wear to be the primary wear mechanism accompanied by adhesive wear. The investigation concluded that AlTiN has better wear resistance properties and can be used to coat titanium implants for biomedical application. The result shows that the minimum WML and COF have been found at applied load 15 N, sliding speed at 0.5 m/s, and sliding distance 500 m.

“…Alternatively, Druga et al [134] discovered that for Ni-W alloy coating, both wear rate and CoF are significantly increased by the presence of a prevailing amorphous phase. Hussein et al [135] studied the mechanical and tribological properties of NC TiN deposited using the CVD process. The crystallite size of deposition is 10.33 nm and deposition layer thickness is 5 µm.…”

Nanostructuring is a commonly employed method of obtaining superior mechanical properties in metals and alloys. Compared to conventional polycrystalline counterparts, nanostructuring can provide remarkable improvements in yield strength, toughness, fatigue life, corrosion resistance, and hardness, which is attributed to the nano grain size. In this review paper, the current state-of-the-art of synthesis methods of nanocrystalline (NC) materials such as rapid solidification, chemical precipitation, chemical vapor deposition, and mechanical alloying, including high-energy ball milling (HEBM) and cryomilling was elucidated. More specifically, the effect of various process parameters on mechanical properties and microstructural features were explained for a broad range of engineering materials. This study also explains the mechanism of grain strengthening using the Hall-Petch relation and illustrates the effects of post-processing on the grain size and subsequently their properties. This review also reports the applications, challenges, and future scope for the NC materials.

“…After the stent is implanted in the body, the surface of the stent material will interact with the physiological components; protein adsorption and activation, blood cell destruction and an intimal increase occur at the interface between the material and blood. In order to improve the blood compatibility of the stent surface, some researchers have reported that surface modification of inorganic coatings of the stent surface can be employed to improve blood compatibility, such as a Ti-O coating [2][3][4], TiN coating [5,6], diamond-like carbon [7][8][9][10][11][12], etc. Although the blood compatibility has been improved via these inorganic coatings, the above coatings cannot be widely used in vascular stents because of their brittleness.…”

Surface modification of some metal coatings is usually used to improve the blood compatibility of biomaterials; however, some aspects of the bological properties of metal coatings cannot be adjusted via the content of each component. In this work, Cu/Ti metal coatings with various amounts of copper content were prepared by the physical vapor deposition (PVD) method, and the influence of deposition bias was further investigated. Phase structure, element composition and surface morphology were investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy, respectively. The hemolysis ratio, platelet adhesion and protein adsorption were applied to evaluate the blood compatibility. The results show that a Cu/Ti coating of uniform quality can be obtained; the dispersion of the deposition and copper content is regulated by the number of copper sheets, but the deposition bias does not obviously affect the copper content of the Cu/Ti coating. The hemolysis rate of the Cu/Ti coating is less than 0.4%, the degree of platelet adhesion is significantly reduced on Cu/Ti coatings compared to control samples, and the contact angle of all coatings is greater than that of pure titanium. The largest adsorption capacity of BSA was found on the coating with the deposition bias voltage of −40 V. The number of copper flakes is increased, and the adsorption of FIB on the Cu/Ti coating surface is reduced. Therefore, Cu/Ti coatings prepared via this deposition method have potential for applications to regulate blood compatibility and surface performance.
