“…XPS measurements made on the PANi-coated steel after corrosion tests in the high pH electrolyte showed predominantly the benzenoid structure, where the nitrogen is bonded to carbon through a single bond (-NH -). It was shown previously that the reduction of the emeraldine base form of PANi to the reduced form, leucoemeraldine, is due to the redox capability of PANi inducing protective surface oxide formation on the steel surface [17].…”

Cyclic polarization measurements made on steel, iron oxalate-coated steel and polyaniline in a high pH solution and in the absence of chloride ions showed no tendency of the surface towards pitting corrosion. In all cases, the pitting potential was similar to the protection potential. Chlorides in the caustic solution caused significant pitting in the bare steel and slight pitting in the oxalate coated steel. The polyaniline coated-steel showed no pitting in the chloride-containing alkaline solution. Scratches through the polyaniline coating did not initiate pitting in the polyaniline coated steel surface when tested in the chloride-containing solutions. q

“…Alkaline zinc plating zinc plating industry has always been one of the best options for the rust-preventive metallic iron [1][2][3][4], pure zinc and zinc alloy plating to replace the zinc plating has been published [5][6][7], but pure zinc plating is still the most simple, reliable and high-cost method of corrosion. Because corrosion of zinc coating can be isolated from the outside of the coated surface of the substrate, and also includes a cathodic protection [8].…”

High current density on electroplating smooth alkaline zinc coating

et al. 2017

Abstract. The behaviours of the Zinc coating would be subjected to the complex zinc anion, and also the additives, current densities and compositions of electroplating bath. In this study, the complex agents (anise aldehyde and Lugalvan P) were added into the electroplating bath to improve the anti-corrosion ability and inhibit dendritic structure on zinc coating. The Lugalvan P is added into the electroplating bath to inhibit dendritic structure during electroplating. The anise aldehyde and complex zinc ions plate a smooth zinc coating. Moreover, the crystalline structures of zinc coating analyzed by X-ray diffraction analyzer (XRD) and the surface morphology of zinc coating was observed by the scanning electron microscope (SEM). The results show that the Lugalvan P additive forms the relatively highest flatness, which inhibited the dendritic structure. High electroplating efficiency was achieved of current intensity of 3 A cm -2 , and a smoothness and gloss deposited surface could be obtained. With increasing the deposition current density, it can form a better zinc coating with low plating bath resistance to form a higher anti-corrosion zinc plate.

“…Several investigations have been carried out to determine the effects of experimental factors such as plating temperature and current density, on current efficiency and coating properties such as microstructure, abrasion and corrosion resistance [8][9][10][11][12][13][14][15][16][17][18]. Furthermore, a modification of the polarisation form (i.e.…”

Multicriteria optimization of mechanical and morphological properties of chromium electrodeposits under reverse pulse plating

et al. 2007

In this work, a central composite design experiment was performed to estimate the effect of the electroplating parameters (temperature of electrolyte, cathodic and anodic pulse current densities, and cathodic and anodic pulse lengths,) on four properties of hard chromium electrodeposits. The studied responses were the hardness (Hv), the roughness quantified by the two criteria R a (nm) and R (lm)), and the specific abrasive energy, E s (lJ lm -3 ). Analysis of the responses using optimal path technique did not lead to a common set of experimental conditions which fulfilled the required properties. Thus, the desirability function approach has been employed in order to find the best compromise between the different experimental responses. The optimal conditions are: electrolyte temperature: 49.9°C; cathodic pulse current density: 42.0 A dm -2 ; anodic pulse current density: 51.5 A dm -2 , cathodic pulse length: 6.23 s and anodic pulse length: 28.5 ms. Under these conditions, the estimated response values are 738 Hv, 262 nm, 2.61 lm and 0.027 lJ lm -3 for hardness, R a , R and specific abrasive energy respectively, validated experimentally. The resultant coating, examined by AFM, exhibits a nodular fine-grained morphology.
