IMT 44-2022 Bachelor or Master Thesis: Surface performance and optimization of Nickel Titanium alloy electropolishing parameters


Institut für Mikrostrukturtechnik (IMT)

Ihre Aufgaben

Nickel titanium alloys are widely used in different fields, such as biomedicine, machinery and electronics, and aerospace, because of their shape memory effect, superelasticity, and corrosion resistance. Surface treatment on nickel titanium alloy is necessary to reduce metal ion released in human tissues and prevent human poisoning and organ failure.

This position will explore an electropolishing method for optimizing the surface quality of nickel titanium alloy pipes. A hybrid electropolishing solution suitable for nickel titanium alloy pipes was determined through experiments. The key factors affecting the electropolishing process were analyzed and the best polishing parameters were obtained through orthogonal experiment and single factor experiment.

To carry out the work, the IMT has extensive state-of-the-art equipment (600 m² clean room, rapid prototyping processes such as 3D printing and laser cutting, assembly and joining technology laboratories, various metrological laboratories). Intensive support ensures that the work can be carried out within the given time frame.
