Research on the elasto-plastic properties of the coating using the reverse analysis method

The cytotoxicity and bioactivity of binary Ti-40Nb and Ti-10Sn and ternary Ti-10Nb-5Sn alloys, candidates for bioengineering applications, have been studied in view of establishing their osteogenic potential compared to that of c.p. Ti. Cellular population growth was used to assess proliferative (using PrestoBlue) and differentiative phenotypes (via protein and Alkaline phosphatase markers), coupled with gene expression (i.e. Runx2 and OCN) to confirm maturation. Their physical (i.e. wettability reported as contact angle, electrical state near the surface, i.e. surface Z potential) and chemical properties (i.e. oxide layer thickness and composition, (esp. TiO2 % content)) were analysed independently from topology and roughness (data provided).

This work is to rationally designed and constructed a novel micro/nano oxide multistructures on Ti alloy surface using HF/HCl etching and IHT oxidizing. The IHT technology is a kind of a rapid, economical, environmentally friendly and easily processable method based on the inherent skin effect of induction current, which is very suitable for being used in surface multifunction of Ti-based biomaterials. Besides, exploring the rapid construction method of bioactive multiscale structures and their biological mechanism derived us to carry out this work. The novelty of this study was to explored the developing tendency of hierarchical structures in further clinical application of high-performance bone implants.

The data corresponding to the surface characteristics, XRD diffractograms, potentiodynamic curves and hydrogen evolution measurements of the studied materials are available.  

Data for wear and friction Transmission Electron Microscopy Natural Sciences

The single magnetron sputtering technology has great limitations in the further optimization of the mechanical properties of TiN films. High energy shot peening (HESP), as a simple and efficient surface nanotechnology, has been widely used in the aerospace, mechanical processing and other fields. After being impacted by the projectile, the surface of the substrate will undergo severe deformation that induces nanocrystallization of the surface grains, thus greatly enhancing the surface activity. Combining HESP with high power impulse magnetron sputtering (HIPIMS)to understand how HESP affects the growth of TiN films on a TA2 surface and whether it can improve the wear resistance of TiN films has important research significance.
