“…Autocatalytic coatings such as nickel-phosphorous offer defect-free solutions if deposited correctly but composite electroplating allows the co-deposition of fine particles of metallic or non-metallic compounds into the plated layers in order to improve the surface properties. Lekka et al [87] compared the performance of pure nickel and Ni-SiC nanostructured coatings and the results indicate that the codeposition of nickel and SiC nanoparticles leads to uniform deposits possessing 1.6 times higher abrasion resistance and double the corrosion resistance to salt spray attack as well as more stable friction under wear-corrosion conditions. Benea et al [88] studied the wear-corrosion performance of these coatings in a 0.5 M Na 2 SO 4 neutral solution.…”

This paper reviews the available literature relating to the emerging research into the performance of coatings under combined wear and corrosion conditions. Understanding how coatings perform under these tribo-corrosion conditions is essential if the service life of equipment is to be predicted and to allow service life to be extended. Therefore, the tribo-corrosion performance of coatings deposited by a variety of techniques is discussed and the main mechanisms associated with their degradation under combined wear and corrosion highlighted. Coating composition, microstructure, defect level, adhesion, cohesion and substrate properties are seen as some of the critical elements in coating performance when subjected to tribo-corrosion contacts. The importance of post-coating deposition treatments such as laser resurfacing and sealing are also discussed. Interactions between wear and corrosion mechanisms are identified along with some models and mapping techniques that aim to inform coating selection and predict performance. Recent investigations into mono-layer as well as multilayered and functionally graded coatings are reviewed as candidates for wear-corrosion resistant surfaces. The review reveals the need for a more considered approach to tribo-corrosion testing and the way in which the results are analysed and presented. For example, the test conditions should be appropriate to the coating system under test; the level of in situ instrumentation deployed and the post-test analysis of in situ electrochemical data should be carefully selected as well as details given of the composition of any surface tribofilms formed and the identification of the degradation mechanisms.

“…been shown that not only the SiC layer but composite layer containing SiC particles can be also used to improve the chemical resistance of a coating layer; improved corrosion resistance was found by introducing SiC-particles to electrolytic nickel layer [12,13]. It has been also shown that the corrosion resistance of Ni-Co/SiC nano composite coatings depends on the size of SiC particles; it was much better if SiC nano particles were used than in case if the composite contained micro sized SiC [14].…”

“…On the other hand these layers are far from being perfect SiC. Rather, they are layers containing most likely defective amorphous SiC together with other components like C, Si and Ga. Based on the literature [12][13][14] one might hope that even such layers have high (compared to "usual" materials) resistance against chemical attack. Thus, we have studied the chemical resistance of these layers as a function of their thickness.…”

“…A similar weight loss tendency was observed in coatings reinforced with alumina particles. Nearing studies conducted authors of article [16]. Comparing the abrasion resistance of Ni and Ni-SiC coatings they found that abrasion resistance of composite Ni-SiC coatings is about 37.5% higher than the coating of pure nickel one.…”

In this study, Ni, Ni-SiC and Ni-Al2O3 coatings were electroplated on the 2xxx series aluminium alloy. The following parameters of the electroplating process were applied: current density -4A/dm 2 , time -60 minutes, and temperature -60°C. Hard particles of submicrometric size were used. The results of the research showing the effect of the addition of hard particles (introduced into the nickel bath as a dispersed phase) on the properties of coatings, including the effect of the type (SiC or Al2O3) and content (0, 25, 50 g / l) of these particles, were discussed. Based on extensive investigations, it was found that the type of ceramic particles significantly affects the structure of produced coatings. The dispersed particles incorporated into the nickel coatings improve their abrasion resistance. Improving of the corrosion properties were observed only in the case of coatings containing silicon carbide particles.
