Surface performance and optimization of Nickel Titanium alloy electropolishing parameters

 

Work's Description:

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.
