<p class="AMSmaintext1"><span lang="EN-GB">In this paper, we are interested in the study of electrochemical, morphological and structural characteristics of the properties of the deposits of Zn-Ni-TiO<sub>2</sub> obtained by electrodeposition on the mild steel substrate in a bath of sulfate. The principal aim is to improve the coatings with better properties, by incorporation of titanium oxide, which is a hard compound, chemically stable and irreducible. The characterization of the coatings was carried out by scanning electron microscopy (SEM) and by X-ray diffraction. The morphology of the film surface varies with the concentration of oxide titanium and it was found higher values of microhardness. Electrochemical characterization of the composites had been carried out through potentiodynamic polarization. The results showed that better corrosion resistance with the incorporation of oxide titanium.</span></p>

Two type of ceramic composite coatings of Fe-Cr-B alloy reinforced with cobalt-coated tungsten carbide (WC-Co) particles or nickel-coated tungsten carbide (WC-Ni) particles were deposited on a mild steel substrate by arc spraying, respectively. The microstructure of the coating was investigated by optical microscopy. X-ray diffraction analysis was used to study the phase composition in the coating. The microhardness of the coating was determined. The wear behavior of the coating was evaluated. The results showed that the WC-Co/FeCrB coating has the excellent abrasive wear resistance which is about 11 times higher than that of Q235 mild steel. The main wear mechanism of both coatings was silica scratching and micro-cutting of the matrix and the resultant pulling out of WC particles.
