Effect of surfactant concentration in the electrolyte on the tribological properties of nickel-tungsten carbide composite coatings produced by pulse electro co-deposition

Preparation and characterization of pulsed electrodeposited cobalt–graphene nanocomposite coatings

“…2 They are simple, cost effective, and can be scaled up for larger components. 3 Nanocomposite coatings based on cobalt (Co), tungsten (W), carbon nanotubes (CNTs), nickel (Ni), molybdenum (Mo), and zirconium (Zr) have been developed by pulsed electrodeposition techniques. [4][5][6][7] Graphene is a two-dimensional (2D) sp 2 -hybridized carbon nanomaterial with one-atom thick structure.…”

Effect of surfactant concentration in electrolyte on the fabrication and properties of nickel-graphene nanocomposite coating synthesized by electrochemical co-deposition

“…Their results indicated that as the content of WC was increased in the coatings, higher hardness and better wear resistance of the coatings were obtained with the increasing concentration of SDS in the electrolyte. Kartal et al 22 reported the effect of the surfactant SDS on the properties of Ni-WC composite coatings and found that the homogeneity of the WC dispersion increased and the mechanical and tribological properties of the composite coatings were improved significantly with the increasing concentration of SDS in the deposition process. A. Zarebidaki and S. R. Allahkaram 41 investigated the influence of the SDS surfactant on the deposition behavior of Ni–P-CNT composite coatings.…”

Combined effects of ALS and SLS on Al2O3 reinforced composite nickel coatings

“…There are several studies in the literature on electrocodeposited Ni-Al 2 O 3 composite structures. Most of these studies focused on Watt's plating bath and only some of them are cited here [8][9][10][27][28][29][30][31][32]. There are comparatively fewer studies on sulfamate plating bath [15,26,[33][34][35][36][37] and none of these studies used ALS as the surfactant.…”

“…While moving to the cathode, nickel ions are adsorbed by the negatively charged second phase particles and carry them to cathode surface to form a MMC coating [4]. The addition of many second phase particles including AlN [5], MoS 2 [6], TiO 2 [7], Mo [8], graphite [8], TiO 2 -TiC [9], WC [10,11], CeO 2 [12], diamond [13], W/diamond [14], graphene [15], Al 2 O 3 –TiO 2 [16], Al 2 O 3 [17,18], WS 2 [19], B 4 C [20], La 2 O 3 [21], SiC [22], SiC-W [23] and ZrO 2 [24] to the nickel matrix have been studied previously to modify the surface properties.…”
