Thermal Spray Coatings on Titanium

The geometric form of a prosthesis and the material for its manufacture are determined mainly by the static and dynamic loading requirements during daily use. Mechanical stability over time is required, and the device must therefore have the ability to withstand stress and strain up to the elastic limits of the construction. Additionally, temperature response must be considered as well as chemical stability. For medical devices, acceptance by the surrounding tissue must be ensured. Properties such as bioinertness, biocompatibility or bioactivity are a few characteristics of materials claimed to be biomaterials [1] or medical devices. The interactions with human body fluids and tissues take place at the interface and are determined mainly by the surface characteristics of the component.
