Additive manufacturing (AM) opens a new approach for production of metallic materials. For nitinol, this method can be considered as 4D printing where the functionality of the material depends on both AM process, where rapid cooling is involved, and post processing.
The surface properties of AM parts are limited due to process characteristics and post processing of printed materials is often required.
In this study we produced AM nitinol samples and characterized the chemical, metallurgical and thermo-mechanical properties of the parts before and after post-processing.
Advanced surface technologies were used for improvement of the parts including different chemical and electrochemical processes, from conventional ones (etching, polishing, EP, etc.) to new processes that are being investigated and developed in our labs (plasma EP, magnetic EP, etc.).
The metallurgical and chemical effects of these processes were investigated in order to find a proper solution for AM nitinol parts for various industrial applications.
