Titanium-based materials are the most widely used in biomedical applications. However, according to literature findings, degradation products of titanium have been associated with potential allergic reactions, inflammation, and bone resorption. The corrosion process Ti-6Al-4V human body environment may be exacerbated by factors such as reduced pH levels elevated concentrations chloride compounds. Coatings made biopolymers gaining attention they offer numerous advantages for enhancing implant...
Abstract Herein, we analyzed the morphology of atmospheric plasma-sprayed (APS) coating on medical 316L stainless steel and its influence physical electrochemical properties implant application. Five types coatings were examined: hydroxyapatite (HAp), titanium (Ti), zirconium (Zr), Ti/HAp Zr/HAp. The base via chemical phase composition, surface topography, wettability in particular corrosion resistance Ringer solution immersed conditions potentiodynamic test, EIS analysis. APS pure HAp...

Surface modification techniques play a major role in shaping the physicochemical properties of 316 LVM steel used for implants. The utilised methods surface layer must ensure repeatability and uniformity physical chemical properties. structure composition implants can be modified using various methods, among which anode oxidation sol‐gel are dominant. One more important aspects related to maintaining (e.g. vessel stents) is ensuring maintenance their geometric characteristics along entire...
This paper discusses the impact of coal abrasive materials varied petrographic composition and claystones containing admixtures matter on surface wear wear-resistant martensitic steels. Wear tests were conducted at a test stand for three varieties hard coal: vitrinite, clarinite, durinite, five samples claystone. These revealed no significant effect type used value mass loss from steel samples. The reason behind foregoing is observed tendency abrasives, irrespective their variety, to...
The effect of 2 mass% rare earth elements (RE) as in mischmetal state on the structure, thermal behaviour and mechanical properties Mg–xLi–4Al (x = 4, 8 12 by mass percentage). thermo-derivative analysis was implemented using UMSA platform (Universal Metallurgical Simulator Analyzer) with cooling rate approx. ≈ 0.6 °C s−1 that correspond to natural cooling.

Abstract This study used the dip-coating method to develop a new biocompatible coating composed of polylactide (PLA) and casein for ZnMg1.2 wt% alloy implants. It evaluated its impact on alloy's degradation in simulated body fluid. After 168 h immersion Ringer's solution, surface morphology analysis showed that PLA-casein coatings demonstrated uniform degradation, with corrosion current density measured at 48 µA/cm 2 . Contact angle measurements indicated average contact angles...
Abstract In the work it was demonstrated that exploitative stability of edges from tool ceramics and sintered carbides coated with gradient multilayer PVD CVD coatings depends mainly on adherence to substrate, while change coating microhardness 2300 3500 HV0.05, size grains their thickness affect durability a lesser extent. It found some showed fine-grained structure. The which contained AlN phase hexagonal lattice considerably higher adhesion substrate sialon rather than containing TiN...
