“…The difference in hardness provides compelling evidence that the hardness of the eroded surface in NiTi surpasses that of SUS630, consequently establishing a plausible link to heightened drag forces and augmenting wear resistance. Lastly, a study that compared TiC-stainless steel and TiC-NiTi blend also corroborated that the NiTi blend revealed better wear resistance of 0.4 mg/min over the TiC-stainless steel of 4.0 mg/min [75]. The present study posits the significance of the Oka wear model as a more pertinent consideration in the investigation of sand screen wear.…”

This research explores discrete element method analysis to investigate the wear of NiTi Sand Screens in comparison to traditional materials. The study utilized Altair EDEM v2022.2 software and employed Oka and Archard models to simulate the wear behavior of Nitinol, a well-established Shape Memory Alloy (SMA). The mechanical properties considered include Poisson’s ratio, solid density, shear modulus, and Young modulus. Results indicate significantly higher wear values and deformations with the Oka model compared to negligible wear with the Archard model. The Oka model’s emphasis on impact as the primary wear mechanism, supported by high normal cumulative energy, better represents sand screen wear phenomena. Additionally, this study indicates that factors such as particle size distribution and normal and tangential cumulative contact energy hold potential as predictors of wear response and characteristics. The Oka model demonstrated that NiTi exhibited reduced wear losses compared to SUS630 and Cr–Mn white cast iron, both of which are recognized for their high toughness when subjected to an impact load. Experimental analysis validated the simulation findings with morphological and graphical erosion plots. The limitation of observing the shape memory effect through DEM (discrete element method) simulation was acknowledged. Recommendations include characterizing post-wear microstructural changes, exploring the influence of temperature on wear behavior, and further research to refine wear models and understand SMA sand screen responses.

“…In addition, by adding TiC particles to the NiTi SMA, the wear resistance was improved when an optimal fraction of 60% was used [144,145]. The composite coating not only improved the wear resistance, but also enhanced the bio-compatibility of NiTi SMAs [146,147].…”

In this research, the corrosion behavior of different types of (Ni-TiC) coatings produced by high velocity oxy-fuel (HVOF) technique was studied. Ni-TiC and Ni-(Ti,W)C composite powders were produced by self-propagation high temperature synthesis (SHS). These powders as feedstock were thermally sprayed on steel substrates in comparison with a conventional powder mixture of Ni þ TiC. The microstructures of the produced coatings were characterized using SEM micrographs. The presence of different phases in the microstructure was investigated using EDS analysis and XRD patterns. Also, the behavior of the coatings against a corrosive media was studied using Tafel polarization tests. The results show that the Ni-TiC and Ni(W-Ti)C coatings exhibited better corrosion resistance than conventional Ni þ TiC mixture coating due to the increment of the homogeneity of the structure and the decrement of the porosity level. In addition, the presence of W in the microstructure of Ni(W-Ti)C coating provided the least pitting and highest general corrosion.
