Study of Particle Incorporation and Performance Characteristic of Aluminium Silicate-Zirconia Embedded on Zinc Rich Coatings for Corrosion and Wear Performance

Abstract

Composite coatings of Zn-Al6O13Si2 and Zn-Al6O13Si2-ZrO2 were electroplated on mild steel from Zn 2+ ions bath and homogeneously dispersed nano Al6O13Si2-ZrO2 particulates were achieved. The corrosion resistance characteristics of the deposited coatings were evaluated by linear polarization method. The microstructural properties of the multilayer produce coatings were examined by scanning electron microscope equipped with energy dispersive spectrometer, X-ray diffraction and atomic force microscope. The thermal deformation were observed in 250 ºC for 4 h and mechanical properties of the composite coatings were investigated using diamond base Dura scan microhardness tester. From the observed results, it was shown that the incorporation of particles into the electrolyte change the microstructure characteristics of developed composite and improved drastically the thermomechanical performance of the coatings.

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

“…The deposition was done using the setup shown in Fig 1 and the produced coated substrate shown. The choice of the varied deposition parameter stems from the literature [16,22]. Mild steel (MS) substrate as cathode material and the zinc as the anode material were duly connected to the rectifier and immersed into the deposition bath setting the stirring rate to 400 rpm, temperature to 75℃ and time to 15 mins.…”

“…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.…”

Data on inhibitive performance of chloraphenicol drug on A315 mild steel in acidic medium

“…The electrochemical process was performed using Autolab potentiostat galvanostat equipment (PGSTAT 101), NOVA 2.1 software and a 3-electrode cell containing 100 ml of 0.1 M Hydrochloric acid (with and without inhibitor) at 30 °C. A graphite rod was used as the auxiliary electrode, silver chloride electrode (Ag/AgCl) was used as the reference electrode and the mild steel coupon was connected to a specimen holder to serve as the working electrode, as carried out in previous work [1] , [2] .…”

“…The bath preparation for electrochemical (corrosion) process was designed with varied concentration of chloramphenicol as corrosion inhibitor (2.5–10%). Total time duration of 360 h was considered for the experiment, but with intermittent weighing of the mild steel in every 72 h [1] , [2] , [3] , [4] .…”

Molecular Dynamics Simulation of Interface Properties between Water-Based Inorganic Zinc Silicate Coating Modified by Organosilicone and Iron Substrate

“…The binder is mainly high modulus silicate solution, including lithium silicate, sodium silicate, potassium silicate. There are a lot of -Si-OH bonds in silicate solution and they react with zinc powder to form a network complex of zinc silicate [37,38]. At the same time, the silicate can also react with iron atoms of metal substrate surface to form zinc iron silicate with excellent adhesion.…”
