“…Here, we extended these works by employing TFMG-coated dermatome blades to split-thickness skin graft surgery involving the skin of a live pig. We also investigated the performance Fe-based TFMGs 22–24 on dermatome blades. Our aim was to promote the healing of wounds induced through surgery and investigate the influence of hair in these procedures.…”

In this study, we sought to enhance the cutting properties of the various blades by coating them with Zr- and Fe-based thin film metallic glasses (TFMGs) to a thickness of 234–255 nm via sputter deposition. In oil-repellency/sliding tests on kitchen blades, the sliding angle and friction forces were as follows: bare blades (31.6°) and (35 µN), Ti-coated blades (20.3°) and (23.7 µN), and Z-TFMG coated blades (16.2°) and (19.2 µN). Comparisons were conducted with bare blades and those with a Teflon coating (a low-friction material commonly used for the coating of microtome blades). We also found that the Teflon coating reduced the cutting forces of an uncoated microtome blade by ~80%, whereas the proposed Z-TFMG achieved a ~51% reduction. The Z-TFMG presented no indications of delamination after being used 30 times for cutting; however, the Teflon coating proved highly susceptible to peeling and the bare blade was affected by surface staining. These results demonstrate the efficacy of the TFMG coating in terms of low friction, non-stick performance, and substrate adhesion. The performance of Z-TFMG and F-TFMG was also evaluated in split-thickness skin graft surgery using dermatome blades aimed at elucidating the influence of TFMG coatings on the healing of surgical incisions. When tested repeatedly on hairless skin, the surface roughness of uncoated blades increased by approximately 70%, whereas the surface roughness of TFMG-coated blades increases by only 8.6%. In the presence of hair, the surface roughness of uncoated blades increased by approximately ~108%, whereas the surface roughness of TFMG-coated blades increases by only ~23%. By Day 7, the wounds produced using TFMG-coated blades were noticeably smaller than those produced using uncoated blades, and these effects were particularly evident in hairy samples. This is a clear demonstration of the efficacy of TFMG surface coatings in preserving the cutting quality of surgical instruments.

“…The effective capacitance ( C dl ) of the electrochemical double layer was evaluated using Brug's formula: 48 C eff = Q 1/ n ( R s −1 + R ct −1 ) ( n −1)/ n where Q is the magnitude of the CPE. Based on the calculated C dl , the thickness of the EDL ( d eff ) can then be calculated as follows: 49 where ε 0 (8.8542 × 10 −14 F cm −1 ) is the permittivity of vacuum and ε r is the dielectric constant (taken as 15.6 here 50 ).…”

“…The various synthesis routes used to produce the metallic glass coatings are pulsed laser deposition (PLD), magnetron sputtering, laser cladding and thermal spraying [85,86,108,109,[110][111][112][113][114]. Both PLD and sputtering techniques suffer from a major drawback of low deposition rate, while during laser cladding process stress development in the coatings would be problematic; therefore, synthesizing thicker coatings via these processes is very difficult.…”

Among various materials available for alleviating the corrosion-related degradation, thermal sprayed Fe-based metallic glass coatings (MGCs) have received huge attention from the scientific community due to the exceptional combination of mechanical and corrosion properties, along with commercially attractive low material cost of this particular alloy system. Emerging reports on the thermal sprayed Fe-based MGCs outperforming conventional corrosion-resistant materials and coatings have accelerated further exploration of this domain, resulting in an immense increase of research activities over the last few decades producing fascinating results. This review takes a holistic approach encompassing an in-depth assessment of all the relevant salient work till date, including corrosion properties, corresponding degradation mechanisms, metallurgical and environmental factors with reference to passive film dynamics and/or formation of corrosion products. Moreover, various strategies for improved corrosion properties and recent research progress have been reviewed with an attempt to identify the present knowledge gaps and the future research directions.
