“…In addition, the electrolyte is a low concentration salt solution, which is not easy to cause harm to the environment. 12 At the same time, the technology has high efficiency and excellent polishing effect, and the surface of all kinds of steel, 13,14 copper, 15 titanium, and its alloys [16][17][18] after EPP have been effectively improved. Matthias et al 19 designed, developed, and tested a prototype equipment for internal surface polishing by plasma, which can realize stable polishing of the inner surface of stainless steel pipes at a maximum potential difference of 320 V, with an average surface roughness Sa of 0.065-0.090 mm.…”

Electrolytic plasma polishing is a new type of surface finishing technology, widely used for high-quality polishing of metals and alloys due to its excellent processability. In this paper, the austenitic stainless steel (302) is the processing material, and the electrolyte temperature, electrolyte concentration, voltage, and polishing time are used as influencing factors. The surface roughness of the material is used as the evaluation index for electrolytic plasma polishing experiments. The orthogonal experimental group is designed to obtain the best process parameters of electrolytic plasma polishing through range analysis, and the influence laws of various factors on surface roughness is studied. The property of the polished sample from the aspects of surface morphology, elemental composition, X-ray diffraction analysis, hardness changes, and corrosion resistance are characterized. The experimental results show that the surface profile of the polished sample has better consistency, and overall it is flat and smooth, with the original scratches are completely removed. The surface roughness is significantly reduced from the initial 0.3–0.076 μm. The content of Cr element has increased to a certain extent, while the content of Fe element has decreased, and surface impurities have been removed. There is no phase transition on the surface of the sample, the diffraction peak intensity significantly increases, the half width prominently decreases, the crystalline grain size increases, and the surface hardness decreases. During electrochemical test, the self-corrosion potential increases, the self-corrosion current density decreases, and the corrosion resistance of the sample surface increases.

Separate processes for shape setting and polishing of Nitinol workpieces are well investigated in scientific literature and adopted industrially. However, a simultaneous process for shape setting and polishing of Nitinol has not yet been reported. In this study, preliminary results of such process are presented, providing insights and directions for further research on post-processing shape memory materials. For this purpose, Nitinol wire samples with phase transformation temperatures Af = 4.5 °C, Af = 31 °C and Af = 61 °C were plasma electrolytic polished (PEP) while fitted in a specially designed sample holder at three electrolyte temperatures te = 50 °C, te = 65 °C and te = 80 °C. The PEP process duration was τPEP = 60 s, τPEP = 180 s and τPEP = 300 s. After the PEP processes, the samples were investigated for the shape memory effect (SME). The training effect, known to be present in shape memory alloys (SMA), was taken into account. The surface roughness of the investigated wires was measured before and after the PEP process. The obtained results demonstrate that both a phase transformation temperature and an electrolyte temperature have a strong effect on polishing and shape setting results.
