Corrosion of Titanium: Part 1: Aggressive Environments

2018/7/11Yet, the most commonly used alloy is titanium grade 5, also known as Ti6AI4V, Ti-6AI-4V or Ti 6-4, containing 6% aluminum, 4% vanadium, 0.25% (max) iron and 0.2% (max) oxygen. Titanium is a very reactive metal: when exposed to an aerated environment, a thin titanium dioxide film, approximately 1.5–10 nm in thickness, is formed.

Hot Topic: Carbon, Graphite, and Graphene

2021/3/15Talking about carbon, one automatically thinks of carbon nanotubes and fullerenes. But there is much more to this broad subject area. Advances in graphene research, templating methods, and the emergence of nanodiamonds make this field a rich area of research.

Corrosion Behavior and In Vitro Cytotoxicity of Ni–Ti and

Biocompatible metals that are favorably used as implants such as stainless steel, Co-Cr alloys, Ti alloys and biodegradable Mg and Fe alloys are specifically addressed. We have highlighted the adsorption phenomenon of protein on metallic implants, the interaction of proteins with metallic implants and the role of protein adsorption on implant biocorrosion behavior as well as their wear resistance.
