“…The lower corrosion current density and more positive corrosion potential values demonstrate increased corrosion resistance [13,49]. The presence of secondary phase TiO 2 particles, which act as a barrier against the corrosion environment, can be said to be the reason for the increase in corrosion resistance in composite coatings [47,50,51]. Morover, corrosion resistance of NiB-TiO 2 composite coatings can be attributed to the presence of crystallographic texture and formation of barrier layer after polarization [seen figure 5].…”

In this study, TiO2 particle reinforced NiB alloy matrix composite coatings were produced on steel substrates by using a modified Watts type bath with ultrasonic-assisted pulse electrodeposition (UAPED) method. The average particle size of the TiO2 particles used in the composite coating is 500nm, and the effect of different particle concentrations (0, 5, 10, 15 and 20 g/L) on mechanical and electrochemical properties was investigated. The produced NiB alloy and NiB-TiO2 composite coatings were heat treated at 400 °C for 2 hours, and the properties of the coatings were compared before and after heat treatment. Microstructure and morphology were characterized by scanning electron microscope (SEM). Phases and structures were determined by x-ray diffraction analysis (XRD), and crystalline size and % distortion were calculated from XRD analysis. The hardness measurements of NiB alloy and NiB-TiO2 composite coatings were carried out by microhardness measurement, and the wear tests of composites were carried out by the reciprocating method. Electrochemical measurements of coatings were carried out in 3.5% NaCl solution, and the effect of particle concentration on corrosion behaviour was investigated. The highest hardness value was 1268 HV, and it was obtained at 20 g/L TiO2 concentration and after heat treatment. The lowest crystalline size was obtained 34.4 nm with NiB-TiO2 composite coatings. When the wear resistances were compared with NiB-TiO2 composites and NiB alloy coating, composite coatings' wear resistance increased approximately two times with the effect of heat treatment. In addition, when the coatings are evaluated in terms of corrosion behaviour, the best result was obtained in the composite coating produced with 20 g/L TiO2 concentration. Compared to NiB Alloy coating, the corrosion rate of the composite coating produced with 20 g/L TiO2 concentration was reduced from 32.49 mpy to 11.68 mpy. This indicates an improvement of approximately three times in corrosion rate.

This study aims to improve the corrosion properties of iron materials used in the automotive industry. For this purpose, two different coating techniques were applied to the same surface. As part of the research, different passivation processes (transparent, blue, yellow, and black) were applied to alkaline Zn-Ni coatings. Geomet 321 and Geomet ML Black coatings were deposited on the passivation layer to form a double-layer coating. In order to investigate the adhesion and corrosion effects of these coatings, a dry adhesion test, a water test, a humidity test, and a salt spray/spray test were carried out, and cross-cut adhesion tests were carried out after each corrosion test. After all these tests, rust formation was analyzed by visual analysis, and atomic weight percentages and coating thicknesses were examined by X-ray. Geomet 321 and ML Black coatings, which were tested using different passivation processes, successfully passed. The transparent passivation after the Zn-Ni coating fully satisfied both adhesion and corrosion protection requirements for the 321 and ML Black coatings. No red rust formation was observed on the coating samples after the test; only partial white rust formation was observed, and no peeling of the coating layer was detected in the adhesion tests. As a result, the most favorable results were obtained for the transparent, blue, and black passivated coatings.
