“…Composite coatings are electrodeposited in various types of plating baths, usually of complex composition, reinforced with the additions of ceramic powders in the form of dispersed particles. The most commonly used dispersed particles are: oxides [1], sulfides, borides [2][3], nitrides [4], silicides [5] and carbides [6]. The choice of the compound depends on the type of matrix.…”

The paper presents the results of the electrodeposition of nickel composite coatings reinforced with the ceramic SiC particles. A Watts type galvanic bath modified with various organic additives was used. These additives were: 2-sulfobenzoic acid imide (LSA), dioctyl sulfosuccinate sodium salt (DSS), sodium dodecyl sulfate (SDS), tris (hydroxymethyl) aminomethane (THAM) and hexamethyldisilizane (HMDS). The nickel composite coating was electrodeposited on a 2xxx aluminum alloy series substrate (EN-AW 2017) with zinc interlayer. Studies concerned the effect of the applied organic additives on properties of composite coatings such as: microstructure, microhardness, adhesion to the substrate, corrosion resistance and roughness. The structure of the coatings was assessed by scanning electron microscopy and light microscopy. Based on the studies of zeta potential it was found that the bath modification had a significant impact on the amount of the ceramic phase embedded in metal matrix. The tests conducted in a model 0.01 M KCl solution were not fully representative of the true behavior of particles in a Watts bath.

“…By modification of the composition of electrolyte, in other words, a change of the content of boron particles in the bath, as well as by the use of additives in appropriate concentrations, it is possible formation of the composition and structure of the electrodeposited Ni-B coatings [13,14].…”

The structure and internal stresses were investigated for d.c.‐plated Ni composite deposits prepared from a low‐concen‐tration Watts electrolyte, with and without additive agents and dispersive B particles. The dispersed phase and additives used in the bath were shown to affect the composition and structure of the electrodeposited composite layer. An increase in the content of B particles in the coating and in the size of [111] nickel crystallites led to increased roughness of Ni‐B coatings. The microhardness of the deposited Ni‐B layers increased as the size of [111] nickel crystallites decreased. The internal stresses of the deposited composite coatings depended to a large degree on the additive in the bath. Ni‐B coatings had a (100) texture, with texture (111) and (311) also frequently occurring. Orientation (100) developed even more strongly than in coatings deposited without additives. This shows that in the presence of 3‐(1‐pyridinio)‐propanesulfonate inner salt (PPS), the development of (110), (111) and (311) orientation is blocked. When the additives were used together, the dimensions of the [111] nickel crystallites in all coatings decreased to the smallest dimension in any of the studied coatings. The results suggest that as the effect of the organic compounds employed the nanostructure of the nickel matrix was developed. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
