“…Electrodeposition of stainless steel and Fe-Cr based alloys from Cr (III)-containing solutions has been studied for many years. The main efforts were directed towards studying the influence of electrolyte and deposition parameters on the targeted elemental composition of the films [13,14] and on investigating the mechanisms behind such complex electrochemical systems [15]. As a result, relatively thick (tens of micrometers) coatings with uniform compositions have been produced.…”

Electrodeposition of Fe-Cr-Ni alloy thin films with high corrosion resistance, low cytotoxicity and soft-magnetic properties is reported. Fe-Cr-Ni films with Cr contents from 5 wt% to 40 wt% were prepared by adjusting the current density during electrodeposition and the film properties were investigated. An excellent corrosion resistance was found in films with high Cr contents (≥30 wt%), where anodic polarization performance similar to those of AISI 304 and 316L stainless steels was observed in both acidic and biological media. Cell compatibility, measured by lactate dehydrogenase assay, demonstrated that electrodeposited Fe-Cr-Ni films exhibit low cytotoxicity, comparable to AISI 304 and 316L stainless steels. Unlike AISI 304 and AISI 316L, which are conventional austenite stainless steels, the electrodeposited Fe-Cr-Ni films were found to be amorphous. This leads to soft ferromagnetic characteristics, which are dependent on the alloy composition. The unique combination of excellent corrosion resistance, low cytotoxicity and tunable magnetic properties makes this material interesting for functional coatings and components in advanced biological and medical microsystems.

“…On the other hand, the changes of the intensities -strictly, clearly and directly -indicate the changes of the void concentration. 9 The cluster size is too small to produce the saturation value of positron lifetime (around 500 ps).…”

Our work proves that positron annihilation spectroscopy is an excellent tool to follow the structural changes in chemical species. We present four examples to support the above statement. The sizes of defects in electrodeposited chromium layers were studied and estimated on the basis of positron lifetime spectra decomposed into two components. Vacancies, di-vacancies and vacancy-clusters could be identified in the electrodeposites. The changes of the size distribution of the free volume units in poly(methylmetacrylate) on the dependence of molecular weight and dispersity were described by the correlation between the lifetime of ortho-Ps and the free volume units in polymers. It was found that the free volume is affected by both the molecular weight and dispersity. The effect of dispersity was explained by the sample preparation technique, namely by the application of high pressure. The ortho-para conversion of ortho-Ps was used to follow the partial spin-crossover in lFe(1-ethyl-lH-tetrazole)6](BFD2. The spin-crossover temperature was identified to be 105 K. A conformal structural transformation was found in [Zn(1-propyl-lH-tetrazole)6](BF4) 2 between 170 and 90 K by positronium lifetime measurement and the role of (BF4) 2-anion, in this transformation, was proved by 19F NMR spectroscopy.

“…15 Biocompatibility as a material property can be obtained from very few electrodeposited materials, mainly CrCo and stainless steel such as FeCrNi-based alloys. 16,17 The use of Fe and Ni in a Cr(III)-complex electrochemical system can be found in the literature for FeNiCr [20][21][22][23][24] and FeNiCrMo 25 electrodepositions. However, these works mainly focus on the inuence of deposition parameters on lm features, overlooking the role of the electrochemical reactions on the coating's composition and properties.…”
