“…The NiTi SMAs or Nitinol became popular because of their many applications in various fields like telecommunication, automotive industries, medical and aerospace, etc. [1] including civil industry [2]. The NiTi SMAs have broad application in electromechanical system (MEMS) devices [3], a thermomechanical system for actuators and sensors [4], stent delivery [5], neurology implants [6,7], self-expandable stents [8], orthopedics and cardiology [9], drug delivery systems and implantable devices [10], and eyeglass frames [11] including compatibility for MRI [12].…”

Electrochemical arc machining (ECAM) is a hybrid technique which is discovered by the further development of ECDM. As Nickel-Titanium is a hard-to-cut shape memory alloy, therefore ECAM has been utilized. For any manufacturing industry, the machining characteristics are an essential component of the process for the production of NiTi-based things, therefore in this study, MRR, TWR, over cut, and delamination have been chosen as performance parameters whereas voltage, electrolyte concentration (ethanol with ethylene glycol and NaCl), and tool rotation has been selected as variable parameters. The molybdenum has a low tendency to react chemically, therefore it was chosen as a tool for drilling NiTi. The optimum drilling condition has been detected as 20 v/v% of electrolyte concentration, 0 rpm of tool rotation, and 80V of voltage with help of the GRA-based AHP technique, and further, the GRG was optimized by RSM. The optimum value of the performance parameter has been observed as 101.19 mg/min, 0.006 mg/min, 0.111, and 1.16 for MRR, TWR, OC, and delamination respectively. The SEM analysis revealed HAZ, a white layer, melted droplet, number of cavities, craters, and microvoids near the drilled hole. Furthermore, EDX analysis proved that the work surface can be free of Mo after machining Nitinol by electrochemical arc machining. Also, the XRD analysis revealed the development of carbides like TiC in the melting zone of a drilled hole, where that carbide can vanish the shape memory properties in HAZ. As the electrolyte used is a water-free electrolyte, therefore no formation of oxides was observed.

“…In the present age, component users demand high product quality and improvements. Drives are always being pursued by nitinol-based component manufacturers for excellence in manufacturing (Kedare et al, 2018). However, recently, understanding the changes in the conditions of the nitinol material surfaces is a timely discussion in both surface science and product development agendas.…”

“…However, focusing on the parametric analysis using surface morphology attributes of nitinol could no longer satisfy the requirement for excellent improvement in the surface integrity of nitinol. This is because of the following restrictions: (1) There are several hundreds of components to be manufactured using nitinol, which make the surface integrity improvement task for nitinol a huge challenge to tackle; (2) the complication involved in the surface integrity problem for nitinol trigger a huge difficulty for process engineers and operators of machine centres and drives them to fully utilize the scarce resources available to them for the nitinol-based manufacturing process. Consequently, there is an urgent requirement to install a programme that will ensure the judicious resource utilization and optimum performance of nitinol-based components.…”

When nitinol is machined, quantitative details regarding the surfaces such as the surface crack density, utmost peak-to-valley heights, recast layer thickness and the mean peak-to-valley height among others offer the most appropriate features to consider in the integrity of the surfaces of machined nitinol. This quantitative information directs the integrity and the projected future performance of the machined nitinol in the components. Consequently, the research question of how to achieve optimal surface integrity of the machined nitinol is important. A literature review is conducted to study the surface integrity analysis of wire electrical discharged machined nitinol. In particular, published papers between 2007 and 2021 have been reviewed. Literature is explored concerning the method of analysis, parameters of research interest and the problems/issues arising from the literature. Diverse methods were employed to evaluate the surface integrity of nitinol after machining. Commonly, both mathematical optimization and microstructural characterizations are used to suggest ideas. Mathematical optimization has been in two broad perspectives, namely, experimental design-based methods such as orthogonal arrays, signal-to-noise ratios, Taguchi's utility and quality loss function, Box-Behnken design and response surface methodology. The non-traditional optimization schemes such as the differential evolution, multi-objective optimization based on ratio analysis and teaching learning-based optimization have been applied. For microstructural characterization, tools to evaluate the surface integrity of nitinol such as field emission scanning electron microscope and energy dispersive X-ray have been deployed. Parameters such as residual stress, geometric deviation, microhardness and profile accuracy are pursued to be optimized. It is known that various literature reviews in previous years have studied the surface integrity problem of nitinol using large-scale approaches. However, in this article, a brief review is prescribed and this work reveals how the surface integrity analysis of nitinol has been tackled in the literature.
