Microstructure Formation and Mechanical Properties of Metastable Titanium-Based Gradient Coating Fabricated via Intense Pulse Ion Beam Melt Mixing.

The unique flash heating characteristics of intense pulsed ion beams (IPIB) offer potential advantages to fabricate high-performance coatings with non-equilibrium structures. In this study, titanium-chromium (Ti-Cr) alloy coatings are prepared through magnetron sputtering and successive IPIB irradiation, and the feasibility of IPIB melt mixing (IPIBMM) for a film-substrate system is verified via finite elements analysis. The experimental results reveal that the melting depth is 1.

Micro X-ray Spectral Analysis and Comprehensive In Vivo Study of Modified Titanium Implants.

We developed a technique for the complex modification of the surface of dental implant made of VT1-0 titanium that included sequential mechanical treatment and irradiation with powerful ion beams. The chemical composition and physical properties of the surface of titanium implants (VT1-0 grade) sandblasted with subsequent acid etching, as well as subjected to complex treatment (sandblasting and irradiation with powerful ion beams) were evaluated using micro-X-ray spectral analysis. In in vivo experiments, osseointegrative properties of the implants subjected by these treatments were compared.
