A low-phosphorous Ni-P coating was prepared on a wrought AZ61 magnesium alloy via electroless deposition for 1 h after an adequate substrate-surface pre-treatment. The prepared coating with a thickness of 10 μm was characterized by the uniform distribution of Ni (95.4 % mass fraction) and P (4.6 % mass fraction) in the cross-section. Microcavities present in the coating resulted in quite a low corrosion resistance of the coated magnesium alloy in a 0.1 M NaCl solution. On the other hand, the coating exhibits a high degree of adhesion, as evidenced by a scratch test, and significantly improves the AZ61 magnesium-alloy microhardness. Keywords: electroless nickel, magnesium alloy, AZ61, characterization of Ni-P coatings Malo porozna Ni-P prevleka je bila pripravljena na povr{ini kovane AZ61 magnezijeve zlitine. Prevleka je bila pripravljena z enourno neelektri~no depozicijo na predhodno ustrezno obdelani povr{ini zlitine. Pripravljena prevleka debeline 10 μm je imela v pre~nem prerezu enakomerno porazdelitev Ni (95,4 % masnih odstotkov) in P (4,6 % masnih odstotkov). Zaradi prisotnosti mikropraznin v izdelani prevleki je korozijska odpornost prevle~ene magnezijeve zlitine v 0,1 M NaCl raztopini slaba. Preizkusi razenja prevleke pa so po drugi strani pokazali zelo dober oprijem izdelane prevleke s povr{ino zlitine in znatno izbolj{anje mikrotrdote AZ61 magnezijeve zlitine.

“…If the P content of the EL Ni-P nanocomposite coatings is decreased with the incorporation of nanoparticles, then the ability of the matrix to form the protective layer by hypophosphite anions could be decreased. The findings of Afroukhteh et al [22] help to understand this phenomenon. The EL Ni-P-TiC nanocomposite coatings prepared using 0.01 and 0.03 g/l of TiC fail to show a reasonable level of incorporation of TiC nanoparticles and decreased the P content of the coating.…”

“…When the concentration of TiO 2 nanoparticles is increased from 7 to 9 g/l, the shape of the nodules is decreased further. The formation of EL Ni-P-TiC nanocomposite coatings using varying concentrations of TiC nanoparticles was studied by Afroukhteh et al [22]. Particle-free EL Ni-P coatings exhibit cauliflower-like nodules, which are typical of amorphous material (Fig.…”

“…Subsequently, the nanoparticle suspension is added to the EL plating bath. This procedure is widely used for many types of nanoparticles, viz., SiC [13,14], WC [15], TiO 2 [16], Al 2 O 3 [17], halloysite nanotubes [18], ZrO 2 [19], WS 2 [20] TiN [21], TiC [22] Si 3 N 4 [23] diamond [24], etc. Besides CNTs, ball milling is also considered as a pretreatment for other nanoparticles.…”

This chapter presents an overview of electroless (EL) Ni-P nanocomposite coatings, focusing on their preparation, challenges, and issues on particle incorporation in the metal matrix in terms of dispersibility of nanoparticles in the plating bath, interaction between the nanoparticles and the EL Ni-P matrix during deposition, influence of incorporation of nanoparticles on the characteristics of EL Ni-P nanocomposite coatings, and applications of EL Ni-P nanocomposite coatings.

“…Table 3 shows the coating thickness of nano-composite coating in terms of the SiO 2 concentration during 90 min plating. At higher concentration of SiO 2 nanoparticles, particles have enough opportunity to be entrapped into coating [20] as well as particles start to be agglomerated and higher solution viscosity and lower deposition rate are the results. Table 4 represents the results obtained from the drawing of linear Tafel curves.…”
