Structural and properties of Zn-Al2O3-SiC nano-composite coatings by direct electrolytic process

Anti-wear and Hardness Values of Functional Value-Added Zn-ZnO-Rice Husk Ash Composite Coating of Mild Steel

“…These incorporations have significantly made-up for the shortcomings of zinc. Consequently, development of new surface engineering materials with commendable microhardness, wear resistance and thermal properties has been achieved [14]. Hence, this work anchors on finding the effect of RHA on the microhardness, wear resistance and thermal properties of Zn-ZnO-RHA coated mild steel for defence application obviously not reported prior to this work.…”

“…Also, the efficiency of thin film production is optimally achieved in this case [11]. It is evident from researches that ceramic particles of aluminium silicate (Al2SiO4) [12], alumina (Al2O3) [13], silica (SiO2) [14], silicon carbide (SiC) [15], titania (TiO2) [13], yttria (Y2O3) [16], zirconia (ZrO2) [17], graphene oxide (GO) [18], fullerene (C60) [19] and niobium oxide Nb2O [20] have served as additives in zinc-based electrodeposited coatings. These incorporations have significantly made-up for the shortcomings of zinc.…”

Impact of Applied Potential on the Structural and Non-lubricated Wear Composite Coating in Petrochemical Industry

“…It is obvious that the impediment and the combined effect of TiO2 with aluminum metal provoked decreases in crystallites size, resulting in a strong crystallite distributed across the entire surfaces, which invariably gives solid hard layers. Agreeing to [8,9], titanium composite particles incorporated in Zn matrix can act as seeds for the whiskers growth; [10] added that, through a strengthening mechanism, either via dispersion strengthening or particle strengthening, the whiskers growth will invariably result into higher microhardness. From all these indications, coatings with Zn-Al-7Ti-0.5 V-Cl (289.6 HVN), with higher microhardness value, follow the above assertion.…”

“…The kind of bath constituents is known to influence the nature of coating, and it is stated that properties of binary alloy deposits are advantageous, based on the resilient characteristics of metal or composite embedded in the bath [6][7]. From the assertion made by [1][2][3] [8,9], the plating parameters such as current density, rate of agitation, temperature range, bath constituents' concentration and pH, determine the fraction in which two or more metals uniformly co-deposit to have good surface modified coatings [10]. It is worth mentioning that a significant variation in any one parameter could require a substantial and rewarding alteration in another variable or combination of parameters, to maintain a given design and fabricated coating [1][2][3].…”

A Novel Effect of Solanum Tuberosum/Zn-30Al-7Ti Sulphate Modified Coating on UNS G10150 Mild Steel Via Dual-anode Electrodeposition Route

“…Coating and metal finishing operations are intended to increase abrasion resistance, alter appearance, serve as an improved base for the adhesion of other materials, enhance wear and frictional characteristics, add hardness and improve electrical properties [4]. Electrodeposition is an appreciable technique that has been known to improve functional and high performance applications, especially with thin film fabrication, for outstanding wear deformation resistance, improved hardness, and suitable structural characteristics [5,6]. Acceptable coatings in co-deposition technique are generally characterized by a good adhesion of the coating to the substrate, and low porosity [7].…”
