“…For pure Ni deposits, the internal stress increases gradually with decreasing pH, coinciding well with the previous report. 29 On adding 0.5 g/L H 3 PO 3 in the bath, the internal stress is raised to 136 MPa at pH 3.5. Reducing the pH to 1.5 results in a slight reduction of the internal stress of about 30 MPa.…”

This study describes the effects of the electrolyte pH on phosphorus content, microstructures, and internal stress of NiP deposits prepared from a sulfamate bath containing phosphorous acid. Decreasing the pH increases the concentration of nondissociated phosphorous acid in the electrolyte, which results in a monotonic increase of the phosphorus content in the deposits. The increase in phosphorus content decreases the grain size but increases the strength of the ͑111͒ texture. Decreasing the pH to about 1.5 can decrease the internal stress dramatically to values close to that of the pure Ni deposited at the same pH. A consistent mechanism of the internal stress evolution in both pure Ni and NiP deposits associated with varying the pH is proposed.

“…The selection of the electroplating bath chemistry gives the required characterizations of the nickel electroplate [13,14]. Nickel electroplating has been studied using various types of baths, such as sulphate, chloride, sulphamate, pyrophosphate, and acetate [13][14][15][16][17][18][19][20]. Acetate electrolytes are particularly appealing due to their inherent low toxicity, affordability and lack of environment impact.…”

The use of low carbon steel is categorized as one of the supporting materials in industrial and technological developments because it has high ductility and toughness. However, low carbon steel has limitations in terms of corrosion resistance. There are several ways to increase corrosion resistance in steel. One of them is by providing a layer of protection on the steel surface. The steel plating method used is the electrolysis method or electroplating method. This study aims to determine the influence of variations in current, voltage, temperature, and time on the thickness of the coating formed on steel. The steel plating process is carried out by electroplating process where the coating material or anode is Nickel (Ni) with dimensions (60 mm x 30 mm x 0,1 mm). In comparison, the coated object or cathode is SK5 steel with dimensions (50 mm x 20 mm x 0,3 mm). The aim of this study is to investigate the effect of Current, Voltage, Temperature, and Time Variations on the thickness of steel using electroplating processes. Moreover, all factors will be optimised to achieve the best thickness for steel. Consequently, the corrosion resistance of SK5 can be significantly improved by increasing its thickness. The current variations were used 1A, 2A, 3A, and 4A; voltage variations were used 3V, 6V, 9V, and 12V; temperature variations were used 30°C, 40°C, and 50°C; and times variations were used 0 m, 5 m, 10 m, and 20 m. Based on the results of research that has been carried out on all samples, it is concluded that current, voltage, temperature and time affect the thickness of the sample in the electroplating process. The current, voltage, temperature and time values are linearly related to the thickness resulting from the electroplating process.

“…Other studies 6 of the thickness of nickel films deposited from nickel sulfamate solutions shoved that the internal tensile stress is quite high initially with films on the order of 0.2-0.5 mils and that an equilibrium value is reached thereafter. The high initial internal stresses are considered to be due to the substrate material; that is, the inmtial deposit attempts to duplicate the structure of the substrates.…”
