Oxidation Kinetics in Titanium
Broadcast Date: 15 October 2020
Hosted by Julius Bonini, Principal Consultant, Metallurgy
Titanium is one of the most widely used metals in alloys for medical device applications due to its strength, corrosion resistance, and biocompatibility, amongst other characteristics.
It also has form versatility (e.g. plates, rods, wire, etc.) and manufacture versatility (e.g. traditional subtractive machining, additive manufacturing, etc.). However, one of the most challenging phenomena with the use of titanium is oxidation. Whether intentional (e.g. anodisation) or unintentional (e.g. alpha case formation), the process by which oxides form must be understood and well controlled to ensure optimal performance of any medical device.
In this webinar, Julius Bonini, Principal Consultant of Metallurgy, explores the various reactions, phenomena, and challenges associated with titanium oxidation, exploring thermodynamics, atomic diffusion, and a whole lot more.
Specific topics include:
- Basics of titanium metallurgy
- Oxygen diffusion
- Oxide formation
- Oxide stability
- Surface treatments that rely on oxidation
