The wear behaviour of electro-codeposited Ni–SiC composites

Electrodeposition of Metal Matrix Nanocomposites: Improvement of the Chemical Characterization Techniques

“…These include oxides such as Al 2 O 3 , ZrO 2 , TiO 2 and Cr 2 O 3 or carbides like SiC, WC, TiC or nitrides like Si 3 N 4 (Bahrololoom & Sani 2005;Jung et al, 2009;Srivastava et al, 2010;Krishnaveni et al, 2008;Stroumbouli et al, 2005;Gay et al, 2001).The metals mostly used are copper and nickel (Low el al., 2006) however other metals like zinc, silver and, alloys have been used (Gomes et al, 2005;Gay et al, 2001;Tulio & Carlos 2009;Muller et al, 2002;Tian & Cheng, 2007). The most studied system has been the Ni-SiC due to its potential technological applications (Low et al, 2006;Hovestad & Janssen 1995;Zimmermann et al, 2002;Hou et al, 2002;Garcia et al 2001;Gyftou et al, 2005;Lekka et al, 2005). Therefore, considering the variety of metals, which can be electrodeposited, electrochemical composite deposition enables the production of a wide range of composite materials that compared to the pure metal coatings have improved physical and (electro)chemical properties (Hovestad & Janssen, 2005).…”

Effect of Surfactants on the Electrodeposition of Ni-SiC Composites

“…Since components of these devices are of micro scale, the second phase material in the matrix needs to be an order of magnitude smaller, thus, up to nanometric requirement [11]. A variety of nanosized particles ranging from 4 nm to 800 nm diameters, have been successfully incorporated into metallic electrodeposits [3,[12][13][14][15][16][17]. By incorporating nanosized particles, properties of the coating such as hardness, wear resistance, strength, scratch resistance, high-temperature corrosion protection, oxidation resistance and self-lubrication, etc., are significantly improved [18,19].…”

“…Various additives have been studied to reduce the agglomeration of particles [30], increasing the volume fraction of SiC particles in the deposit, good dispersion and high hardness. In general, cationic and anionic surfactants are being used to change the surface characteristics of the particles [12,[30][31][32][33][34][35][36][37][38][39][40][41]. Saccharine has been used by Zimmerman et al and Lei Shi et al [22,42].…”

Effects of Sodium Lauryl Sulfate on Co-electrodeposition of Nickel and Fly Ash Particles

“…The surfactants as stimulators can vary compositions, microstructure of matrix as well increase the inert particles amount in deposit [11], because surfactants are able to improve the stability of a suspension by increasing the wettability and surface charge of suspended particles, and also enhance the electrostatic adsorption of suspended particles on the cathode surface by increasing their positive charge [12][13][14][15].…”
