Incorporation of nano zinc oxide for improvement of electroless nickel plating

Microstructural, Surface Topology and Nanomechanical Characterization of Electrodeposited Ni-P/SiC Nanocomposite Coatings

“…Various systems have been developed so far of exceptional in some cases properties. Indicative systems with reinforcing phases, such as Al 2 O 3 [19][20][21][22][23], SiO 2 [24], Cr 2 O 3 [25], ZnO [26], SiC [27][28][29], B 4 C [30], WC [31], CNTs [32,33], Graphite [34], BN [35], Diamond [21,33], Si3N4 [27,36], CeO 2 [37], MoS 2 [38,39], PTFE [40,41], and combinations of them [42,43] are reported.…”

“…The hardness of coatings is of crucial importance and its optimization and improvement is strongly associated with other important properties, such as friction behavior and wear resistance. Various research efforts that are reported in the literature show that the increase of the embedded particle concentration leads to an increase of the overall coating hardness in the case that hard reinforcing particles are co-deposited (carbides, oxides, nitrides) [23][24][25][26][27]37,38] and they may decrease the overall hardness, if soft particles are co-deposited (PTFE for example) [40,41]. However, the main hardness increase is achieved with the post heat treatment.…”

Study on the nano-composite electroless coating of Ni–P/Ag

“…Meanwhile, Gao et al [12] and Balaraju et al [13] found that Al 2 O 3 particles also changed the mechanical properties of composite coatings. Shibli et al [14] studied the incorporation of the nano-ZnO particles resulting in the improvement of metallurgical characteristic and corrosion resistance of the coating. Ni-P-TiO 2 composite coatings were also successfully obtained by Abdel Aal et al [15] and Novakovic et al [16], they found that TiO 2 nanoparticles made the coating finer and smoother.…”

“…[9][10][11][12][13][14][15][16][17][18]. Chen et al [9] and Gao et al [10] synthesized nano-composite coating Ni-P-SiC and explored the influence of heating treatment temperature on the coating properties.…”

Optimization of Conditions for Nanocrystal ZnO in-situ Growing on SiO2-Coated Cotton Fabric

“…

Zinc oxide, a semiconductor with wide bandgap of 3.37 eV, large exciton energy of 60 meV and excellent chemical and thermal stability, has been considered as a promising nanomaterial for a variety of applications such as optical devices, piezoelectric devices, surface acoustic wave filters, photonic crystals, photodetectors, gas sensors, solar cells, and antibacterial and UV protection agents [1][2][3][4][5][6]. Nanoparticle ZnO has been coated on substrates such as glass [7], sapphire [8], and metal [9] through chemical, electro-chemical, hydrothermal, and spin coating methods [7][8][9].Controlling the morphology of nanoparticle growth has become a very important area in nanotechnology research [10][11]. In order to control the morphology and size of nanomaterials, organic additives or catalysts have been used, which cause an increase of impurities in the final products [10].
