Coating solution of yttria-doped zirconia was prepared by using the solgel method and deposited on AISI 304 stainless steel substrates using dip-coating technique. The influence of the mechanical modification of stainless steel substrates and withdrawal rate on the coating quality has been studied. Herein, a novel method based on measuring the electrical capacitance of such coatings is developed in order to assess the coating quality. The method was performed on sanded and polished samples coated at various withdrawal rates, obtaining the greater thickness uniformity for the coatings deposited on polished specimens coated at a withdrawal rate of 25 mm·min ¹1. The results obtained by the proposed method are well in agreement with those found by both optical and electron microscopies. Therefore, such a method seems to be of great interest because of its simplicity and low cost as compared to other well-established techniques, and its results may be a great support for them.

“…Among all surface modification techniques such as chemical vapor deposition [5,6], physical vapor deposition [7], plasma [8], ion implantation [3,4,9,10], and so forth, sol-gel processing has many advantages over other techniques. They include low processing temperature, chemically and physically uniform coatings, high purity, low capital investment, producing thin homogeneous films on large scale, easy controlling of film thickness, and practical in complex geometries effectively [11][12][13][14].…”

Sol-gel 8 wt.% Yttria Stabilized Zirconia (YSZ) thin films were prepared on zirconium (zircaloy-4 alloy) by dip-coating technique followed by heat treating at various temperatures (200°C, 400°C, and 700°C) in order to improve both electrochemical corrosion and high temperature oxidation properties of the substrate. Differential thermal analysis and thermogravimetric analysis (DTA-TG) revealed the coating formation process. X-ray diffraction (XRD) was used to determine the crystalline phase structure transformation. The morphological characterization of the coatings was carried out using scanning electron microscopy (SEM). The electrochemical behavior of the coated and uncoated samples was investigated by means of open circuit potential, Tafel, and electrochemical impedance spectroscopy (EIS) in a 3.5 wt.% NaCl solution. The homogeneity and surface appearance of coatings produced was affected by the heat treatment temperature. According to the corrosion parameters, the YSZ coatings showed a considerable increase in the corrosion resistance, especially at higher heat treatment temperatures. The coating with the best quality, from the surface and corrosion point of view, was subjected to oxidation test in air at 800°C. The coated sample presented a 25% reduction in oxidation rate in comparison with bare substrate.

High chemical stability, resistance to changes in the pH, pressure and temperature meant that zirconium oxide is widely used in many elds. It is used in water treatment and waste water treatment processes, as well as air puri cation. In this paper, selected methods of nano-zirconia synthesis in liquid phase were characterized. ese methods include, among others, the microemulsion method. Based on literature data, the advantages and di culties associated with the use of each method are presented, in order to answer the question of which method of nanometric zirconium oxide synthesis in the liquid phase is the most advantageous. e authors also pointed out some directions of development for the discussed methods, which relate to, among others, solvent change and the use of additives in the form of polymers.Keywords: nano zirconia, hydrothermal method, synthesis, microemulsion method Streszczenie Wysoka stabilność chemiczna, odporność na zmiany pH, ciśnienia i temperatury sprawiły, że tlenek cyrkonu znajduje szerokie zastosowanie w wielu dziedzinach.
