“…The deposition rate for each bath composition was calculated and plotted by Minitab program according to Taguchi orthogonal array L9 for design of the experiment [17][18][19][20], as shown in Fig. 1., It is noticeable that, the increase of nickel sulphate and sodium hypophosphite concentrations in the plating bath, increase the deposition rate.…”

Electroless Ni-P coating is widely used in industrial engineering applications due to its ability to alter and improve the surface properties of the steel substrates. Electroless nickel coating introduce an excellent combination of surface properties, where, it could add brightness, luster, and good appeal. The final coating layer also possess a very good adhesion with the coated substrates, this is the reasons for using such layer as an 'undercoat' for other coatings. The ability to produce a very homogenous composition and produce coating with a high corrosion resistance are mainly based on the plating bath composition. The present work investigates the influence of bath compositions, which included nickel sulphate, sodium hypophosphite and trisodium citrate, on the process of electroless Ni-P coating. The deposition rate (Dr) as well as the bath stability were monitored to optimize the plating bath conditions with the different composition. The results of this work showed that 43

“…Based on information available in the published literature [3][4][5][6][7], it was decided that few experiments would be carried out by varying the following six factors: Based on the prevailing operating situation, the number of factors was chosen to be both high and low. In this specific study, a 16 fractional factorial design with two replicates was chosen.…”

Electroless nickel coating is a revolutionary coating process that can be effectively used to cover a spectrum of alloys and composites, each having its own features. Electroless nickel coatings have been primarily utilized for purposes of both corrosion resistance and wear resistance. Additional qualities, such as overall smoothness of the deposit, low friction, acceptable plating rate, and both electrical properties and magnetic properties, makes them an appropriate choice for a wide variety of applications. Characteristics of the electroless nickel coating are essentially determined by both constituents of the electroless solution, and the conditions used during deposition. Bath temperature, nickel source concentration, and pH of the solution are three key deposition parameters. Furthermore, heat treatment does tend to alter microstructure of the coating and thereby exert an influence on hardness, wear resistance and corrosion resistance. In recent years, researchers have published their findings pertinent to an evaluation of electroless nickel coating on the performance of various types of substrates based on hardness, roughness, corrosion resistance, friction, and wear resistance. Several viable ways aimed at solving the challenges specific to parameter optimization have been put forth in the published literature. In this research study, the electroless coating process was performed based on fractional factorial design. The optimal coating parameters were determined using the Analysis of Variance (ANOVA) approach. The findings reveal bath composition can be used to optimize thickness of the coating.
