Abstract
Herein, we are interested to provide the synthetic methodologies, chemical properties, and the corrosion performance of some Ni-xCo-yTiO2 nanocomposite electroplated on Cu using the gluconate-cysteine bath, pointing at the classification of these materials corresponding to their stability in that simulated marine solution and recommend using these materials in such aggressive media. Electrochemical and spectroscopic measurements were employed in 3.5 wt. % NaCl electrolytes at 25°C. The electrochemical properties of the applicable nanocomposite material will be studied to enhance manufacturing technology and forecast the stability of structures made from it. The produced nanocomposite coatings have been demonstrated to have high corrosion resistance in the investigated electrolyte, which is commonly utilized in hydrogen evolution reaction applications and other novel materials corrosion investigations. By characterizing the corrosion performance of the examined Ni-xCo-yTiO2 nanocomposite coatings in 3.5 wt.% NaCl solution, the Ni-48Co-3.8TiO2 is regarded as the most stable electrode. The results exposed that the inclusion of Co inside Ni-xCo-yTiO2 significantly lessened the corrosion rate of the investigated composites. The surface examination revealed the presence of several materials constituents in the passive layer. DFT and Monte Carlo simulation approaches have been used to investigate and analyze the relationship between molecular structure and inhibitory effect.

期刊介绍:
The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace.
Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
