Opis:
The paper aims to present the main objectives for using magnetic fields to improve process of electropolishing (EP), firstly by focusing on materials and electrochemical systems. The general introduction has been concerned on the sample surface treated under pseudopassivity conditions, in the process generally known as magnetoelectropolishing (MEP). Long-term up-to-date experiments have shown profound changes observed on metals and alloys. The advantageous effects gained by applying MEP to metals and alloys cover: improvement of corrosion resistance, bio- and haemocompatibility, roughness by modification of their surfaces. The improvements are also referred to the mechanical properties of metals and alloys treated by MEP namely: removal of hydrogen, fatigue resistance enhancement, etc. Further developments and the effects of magnetic fields on electropolishing of metals and alloys are to be presented in the next publications.

Opis:
The austenitic cold-rolled AISI 316L stainless steel was used for the studies. Corrosion resistance measurements were performed on the samples after three types of treatments: abrasive finishing (MP), standard electropolishing (EP), and magnetoelectropolishing (MEP). They were carried out in Ringer's solution at a room temperature, indicating a considerable difference in the breaking potential Epit values, dependent on surface treatment. Two groups of samples, those after EP and MEP, were submerged in broth culture wild strain of Escherichia coli from contaminated river water. Images of the steel samples submerged for 2 and 4 hours are displayed in the paper. A statistical approach has been performed. In each case the number of bacteria deposited on the MEP steel samples was higher in comparison with that one noticed on EP samples, increasing much faster with time on the MEP ones.

Opis:
Pure niobium is used for making superconducting radio frequency (SRF) cavities. These cavities need to have a good surface finish to achieve maximum performance. The high smoothness, lack of subsurface hydrogen content and sulfur contamination removal of SRF niobium cavities are the three most important factors to achieving a high accelerating gradient. For finishing niobium surface, electropolishing (EP) in hydrofluoric/sulfuric acid electrolyte is commonly used as a final process. Unfortunately this process had been considered to cause hydrogen absorption that could result in hydrogen Q-disease in niobium SRF cavities. This is why a new electrolyte was compounded to substitute the one presently used. Moreover, the additional imposition of a magnetic field during the electropolishing process (magnetoelectropolishing MEP) not only increases hydrogen removal, but also results in reduction of surface roughness when compared to the roughness achieved by the electropolishing process alone (Rz much over 300 nm). This effect of sharp decrease in hydrogen content was found previously in our experiments with titanium and stainless steels after MEP processing. Our present studies, with the electrolyte consisting of a mixture of 70% methanesulfonic acid with 49% hydrofluoric acid by volume in 3:1 ratio, resulted in intensifying and speeding-up the electrochemical processes of dissolution and polishing niobium surface. It was found that the imposition of a magnetic field of ≈ 100 mT upon the EP process is able to reduce niobium surface roughness of up to 50% (Rz below 200 nm) compared to the roughness achieved by conventional electropolishing.

Opis:
The aim of this study was to compare the pitting corrosion resistance of two austenitic stainless steels, AISI 304L and AISI 316Ti, which are often used for agricultural machinery building. For the corrosion experiments, animal slurry from a pig farm was used. The results obtained from electrochemical corrosion experiments were proceeded by significance tests in Statistica software. The average value of the pitting corrosion potential of AISI 304L stainless steel in the animal slurry is equal 1044.3±146.6 mVSCE whereas the average potential for AISI 316Ti SS equals 1058.4 ±28.3m mVSCE. Corrosion potential of AISI 304L SS is equal 549±80.5 mVSCE, while for AISI 316Ti SS it equals 425.9±80.5 mVSCE. The range of pitting corrosion potentials of AISI 304L SS (364 mVSCE) was over four times higher than that for AISI 316Ti SS (84 mVSCE); the minimum values of pitting corrosion potential for AISI 304L SS (779 mVSCE) was lower than that obtained for AISI 316Ti SS (1012 mVSCE). On the basis of the results it may be concluded that AISI 304L stainless steel is less resistant in case of pitting corrosion resistance than AISI 316Ti SS. For this reason, austenitic AISI 316Ti stainless steel should be used for the transportation or storage of animal slurry.

Opis:
In present work, the results of corrosion analysis of pitting and general corrosion of austenitic duplex 2205 (EN 1.4462) stainless steel in Ringer's solution, are presented. The corrosion rate was studied using potentiodynamic polarisation method by means of the ATLAS 98 potentiostat with POL 98 software. For these measurements the platinum EPT-101 and calomel reference EK-101P electrodes were used. For each run, the electrolytic cell made of glass was used, containing up to 500 ml of the electrolyte. The specimens used for the studies were obtained from a cold-rolled sheet of steel in three forms: as received (without any pretreatment), after abrasive polishing, and after electrochemical polishing. Some of them were passivated for 15 and 30 minutes, respectively, in 20% HNO3 by volume. The study results show clearly that the samples of duplex 2205 stainless steels after electropolishing and passivation for 15 minutes in 20% HNO3 by volume revealed the highest corrosion resistance.

Opis:
The aim of the study was to determine the corrosion behavior of two austenitic stainless steels, AISI 304L and AISI 316Ti, after cold rolling (AR) and mechanical polishing/grinding (MP), in a 32% aqueous solution of AUS (RSM®) Ammonium Nitrate/Urea Solution, used as fertilizer, and compared with the corrosion resistance results obtained in 3% aqueous solution of sodium chloride (NaCl). The studies have shown that cold rolled austenitic stainless steels (AISI 304L and AISI 316Ti) in the 32% aqueous solution of AUS have more than two times higher pitting corrosion resistance than that obtained in 3% aqueous solution of sodium chloride (NaCl). Surface scratch of the cold rolled austenitic AISI 304L stainless steel and submersion of the samples in 3% aqueous solution of sodium chloride resulted in decreasing of its pitting corrosion resistance of more than three times; on the other hand, the pitting corrosion resistance of AISI 316Ti in the same solution decreased of two times. It was found that for both stainless steels (AISI 304L and AISI 316Ti) after mechanical grinding, as simulated by the surface scratch, and submersion of the samples in 32% aqueous solution of AUS, the pitting corrosion resistance was not worsened, because of the passivation properties of AUS solution. The study results have shown that in the natural environments containing aqueous solutions of sodium chloride (NaCl), the use of austenitic stainless steel containing chromium, nickel, molybdenum and titanium (AISI 316Ti) is advised. In other environments without chlorides, such as the AUS fertilizer, the use of austenitic AISI 304L stainless steel may be considered as adequate.

Opis:
In the present paper, the study of pitting and general corrosion of stainless steels used in agriculture, specifically for the agricultural biogas plant constructions, is presented. The austenitic stainless steels AISI 304L, AISI 316Ti, and duplex steel 2205, were investigated. For the evaluation of corrosion resistance, the potentiodynamic studies were performed. General corrosion was determined in the Tafel region of potentiodynamic curve, while pitting corrosion was examined on the basis of the pitting corrosion initiation potential. Based on the studies carried out, it can be stated that the alloyed cold-rolled austenitic stainless steel AISI 304L placed in the environment of the biogas plant ferment has the lowest resistance to pitting and general corrosion of all studied steels. The cold-rolled duplex stainless steel 2205 placed in the same corrosive environment revealed the highest resistance to these types of corrosion. It should be also noted that the pitting and general corrosion resistances of tested alloy austenitic stainless steel AISI 316Ti are higher than those ones of AISI 304L, and less than those ones of duplex steel 2205. In conclusion, as could be expected, the best material for the biogas plant construction is duplex stainless 2205 because it shows the highest resistance to both types of corrosion studied. This steel can be advised as a material for construction of fermentation tanks and heating installations for mixture ferment.

It was found that the obtained coatings, dependent on the PEO process conditions, have pores with different shapes and diameters. The Mg/P and Cu/P ratios by atomic concentration are the same and equal to 0.09±0.01 (by wt %) | 0.11±0.01 (by at%) and/or 0.40±0.08 (by wt %) | 0.19±0.04 (by at%), respectively. That may testify the hydroxyapatite-like structures of Mg-Ti-PO43– and/or Cu-Ti-PO43– have been identified to occur.

Opis:
In the paper, the porous coatings obtained on niobium and two titanium alloys (Ti6Al4V, and TNZ) after Plasma Electrolytic Oxidation (PEO), known also as Micro Arc Oxidation, were studied. The samples were treated at the voltage of 450 V for 3 minutes in the electrolyte consisting of 300 g and 600 g of copper nitrate Cu(NO3)2 in 1 litre of concentrated phosphoric acid H3PO4, consecutively. SEM and EDS studies were performed on the samples. Based on the obtained results it may be concluded that enriched in copper porous coatings on all studied materials were created in the electrolyte within copper nitrate amounting for 600 g. The proposed by the Authors factor to evaluate the obtained coatings, i.e. copper-to-phosphorus ratio, which for the studied materials amounted to 0.21, clearly indicates that the performed electrochemical PEO treatment for surface modification especially of bioimplants may be advised.

In the present paper, the analysis of SEM and EDS results of porous and enriched in calcium, magnesium, zinc, copper and phosphorus coatings, obtained during 3-minute treatments performed by Plasma Electrolytic Oxidation (PEO)/Micro Arc Oxidation (MAO) processes on CP Titanium Grade 2, is presented. The PEO process was carried out at DC potentials of 500 VDC, 575 VDC, and 650 VDC in electrolytes containing 125 g Ca(NO3)2•4H2O, and 125 g Mg(NO3)2∙6H2O, and 125 g Zn(NO3)2∙6H2O, and 125 g Cu(NO3)2∙3H2O in 1 L H3PO4. It was found that obtained coatings have pores with different shapes and diameters and/or size/dimentions. The Ca/P, Mg/P, Zn/P, Cu/P, and M/P ratios (M=Ca+Mg+Zn+Cu) were equal to 0.074, 0.046, 0.056, 0.042, and 0.218, respectively. The highest value of each of these ratios was recorded for 650 VDC. It may be concluded that the obtained PEO coatings structures most likely are similar to hydroxyapatite-like structures, in which the Ca2+ may be replaced with Zn2+, Mg2+, Cu2+.

Based on SEM micrographs it may be stated that the porous surfaces, which are needed for biomedical and catalysis application, are obtained only for samples fabricated at 200 Vpp. It was found out that thickest and most morphologically developed surfaces were obtained at 200 Vpp, too. The surfaces obtained at 250 Vpp and 300 Vpp are cracked and had low concentration of copper, i.e. 0.9 at% and 1.1 at%, respectively, while that one obtained at 200 Vpp was porous and had 8.6 at% copper.

It was found that the voltage of that process influences the chemical composition of coatings shapes obtained on titanium in electrolytes containing calcium, copper and magnesium nitrates. The pores shapes of PEO coatings formed on titanium in electrolytes containing calcium, copper and magnesium nitrates are presented, too. In addition, it was also noted that with using of higher voltage (here 650 VDC) of PEO treatments, the higher Ca/P, Cu/P and Mg/P ratios were found than those after treatments at 500 VDC.
