Data on the effect of incorporation of nanoparticles and process characteristics of Ni–SiO2 coating on oil and gas steel

In this work, data on the effect of process parameter and particle concentration on the developed Ni–SiO2 produced via electrocodeposition were presented. The influence of current density from 0.6 to 1.0 A/dm2 and applied time difference from 10 to 25 min observed on the hardness characteristics and texture performance of the deposited alloy was checked. The weight gained and thickness of surface coverage was acquired and could be further used as a protoype for designing a ternary alloy coating system for oil and gas services.

How data was acquired
The deposition took place in a designed electrodeposition sequence cell containing five steps according to the principle of electrolytic co-deposition route from pre treatment to post treatment. The coating thickness, weight gained, were measured using coating thickness gauge and weighing balance for the weight gain. The weight gain was obtained from the observed weight difference before and after coating. Data format Raw, Analyzed Experimental factors The admixed weight fraction of bath constituent was measured appropriately and electrolyte pH was obtained before the deposition was done and required data acquired.

Experimental features
The depositions were performed between 10 and 25 min at a stirring rate of 100 rpm at room temperature of 25°C. The effect of coating difference on the properties and interfacial surface was acquired, at a current density interval between 0.6 and 1.0 A/dm 2 for the coating duration. The framework of bath condition as it influences the coating thickness and weight gain was put into consideration.

Value of the data
The given data will show author in the field of corrosion engineering with interest in surface improvement the correlation between process parameter influence and incorporated particle on coating performance.
The data obtained for the nickel-silicon dioxide electrolyte can be used as inference to determine the anomalous metal matrix co-deposition of ternary and quaternary alloy.
The data can be used to examine the relationship between the process variable for instance (current density and time) as it affect the nature of coating stability.
The data could be used at investigating the coating progression between the coating thickness, weight gain and the texture of the adsorbed deposits.
The data obtained can be used in investigating the strengthening behaviour of particulate in an electrolyte relating to its mechanical characteristics.

Data
The data generated from the experiment are on variation of coating thickness, weight gain, at constant distance between the anode and cathode with depth of immersion. The depositions process was performed between 10 and 25 min at a stirring rate of 100 rpm at ambient temperature of 25°C.   The data acquired from spectrometer analysis of the mild steel is presented in Table 1. The coating depositions was run twice on two separate mild steel substrate from single electrolyte for all set of sample matrix to ascertain its repeatability in commercial form which is in par with study by Ref. [1]. The influence of coating thickness and weight gain were considered and each variable are acquire twice and the average taken as representative data for better precision. This repeatability in procedure was considered necessary because of the variation in current density and time of deposition to obtained the required data presented in (Tables 2-4).

Experimental design, materials and methods
Mild steel was commercially sourced and sectioned into (40 mm Â 20 mm Â 1 mm) sheet as cathode and 99.5% zinc plate of (30 mm Â 20 mm Â 1 mm) were prepared as anodes. The initial surface preparation was performed with finer grade of emery paper as described in our previous studies [2][3][4][5]. The sample were properly cleaned with sodium carbonate, pickled and activated with 10% HCl at ambient temperature for 10 s then followed by instant rinsing in deionized water. The mild steel specimens were obtained from metal sample site in Nigeria. The chemical composition of the sectioned samples is shown in Table 1 as obtained from spectrometer analyzer. The electrolytic chemical bath of Ni-SiO 2 fabricated alloy was performed in a single cell containing two nickel anode and single cathode electrodes as described by Refs. [6][7][8]. The distance between the anode and the cathode is 15 mm. Before the plating, All chemical used are analar grade and de-ionized water were used in all solution admixed. The bath was preheated at 25°C. The processed parameter and bath composition admixed used for the different coating matrix is presented in Table 2. The choice of the deposition parameter is in line with the preliminary study from our previous work [9] (Table 5).
The prepared zinc electrodes were connected to the rectifier at varying time of deposition and current density between 10-25 min and 0.6-1.0 A/cm 2 . The distance between the anode and the
