“…Stirring of the nickel baths or the rotation of the deposited objects is a partial solution of this problem. However, the addition of surfactants into the nickel bath was shown to be a more effective solution, while the reduction of these microcavities resulted in an increase in the corrosion resistance of the coated substrate [42,43]. Although the plating rate of high-phosphorus Ni-P coatings in [12] was higher, high-phosphorus Ni-P coatings were deposited under more energy-intensive conditions (90 ± 1 • C) [12].…”

Electroless low-phosphorus NiP coating was deposited on a wrought ZE10 magnesium alloy including an advanced pre-treatment of the material surface before deposition. Uniform NiP coating with an average thickness of 10 µm was formed by 95.6 wt % Ni and 4.4 wt % P. The content of Ni and P was homogeneous in the entire cross-section of the coating. Applying the NiP coating to the magnesium substrate, the surface microhardness increased from 60 ± 4 HV 0.025 to 690 ± 30 HV 0.025. Using the scratch test, it was determined that deposited NiP coating exhibits a high degree of adhesion to the magnesium substrate. Electrochemical corrosion properties of NiP coating were analyzed using the polarization tests in 0.1 M NaCl, while the deposited NiP coating showed an improvement of the corrosion resistance when compared to the ZE10 magnesium alloy. Using the scanning electron microscopy analysis, it was determined that the fine morphology of the deposited NiP coating did not contain visible microcavities. The absence of macrodefects due to the adequate pre-treatment before coating was reflected on the mechanism of the coated ZE10 degradation in a 0.1 M NaCl solution.

“…Using hydrophobic polytetrafluoroethylene (PTFE) suspension and an amphoteric surfactant, N‐hexyl N‐benzyl N‐methyl taurines (HBT) in Watt's nickel bath, an electroless nickel‐fluoropolymer composite is generated by electrodeposition (Hamid & Omar, 2003). Similarly, an electroless nickel‐phosphorous (Ni‐P) plating is covered on mild steel by using sulfobetaine (SB3‐14) (Muraliraja et al, 2016). In the case of co‐deposition of copper nanoparticles into the Ni–P matrix, the corrosive hindrance, surface roughness, and microhardness have developed on the substrate by the assistance of the amphoteric surfactant (Banthia et al, 2018; Muraliraja et al, 2018).…”

Amphoteric surfactants have long hydrophobic hydrocarbon chain and hydrophilic positive as well as negative charged center connected with each other by a spacer group. Thus, this type of surfactant maintains overall charged neutrality. The properties of amphoteric surfactants depend primarily on the length of the hydrophobic hydrocarbon chain, the number of methylene segments in the spacer, the positive and negative charged groups, and their relative position. The ionic activity of amphoteric surfactants is influenced according to the pH value of the solvent. They display cationic behavior below the isoelectric points and anionic behavior at a higher pH. They take the shape of zwitterions in the area of the isoelectric point. In fact, amphoteric surfactants can be parted into pH‐sensitive and pH‐insensitive surfactants. The pH‐insensitive surfactants stay as zwitterionic form irrespective of the pH of the solution. This surfactant has some unique features because of its precise molecular structure as follows: high water solubility, high surface activities, a wide isoelectric range, low critical micelle concentration (CMC), high foam stability, low toxicity, low irritating, excellent biodegradability, bioactivity, interface change, and so on. Because of these special characteristics, amphoteric surfactants have been immensely interested in many applications in the scientific community, including cosmetics, chromatography, enhanced oil recovery, electrochemistry, nanoscience, polymer chemistry, and waste water treatment. This review aims to study about amphoteric surfactants, which have only one hydrophobic hydrocarbon tail and two oppositely charged hydrophilic headgroups connected with each other by a spacer group and its properties, applications in various academics and industrial fields.

“…Kennedy et al [8] developed a coating on the TiC microceramic particles using the reactive synthesis method in the composite material and also the presence of air bubbles/porosity in the materials is significantly reduced. Some of the earlier researchers studied the interfacial bonding and phase formation between the solid and liquid phase play an important role in improving the properties of the composite [4,10]. Fan et al [11] studied the coating properties of electroless Ni coating on the ZrO 2 particles under an SEM micrograph and they observed the uniform coating.…”

The braking system is an important component in the automobile sector for transportation. To stop or slow down the vehicle safely, the friction brakes are employed by converting the kinetic energy to heat energy by friction. The interaction of surface materials such as rotor and pad produces heat due to friction and those materials should have a thermally stable tendency to deal with the heat than wear resistance. In this study, for the first time, an attempt is made to check the possibilities of introducing the Mg composite into brake pad applications. The inorganic type friction materials with various components of materials are constantly growing to get the high-performance and low-cost brake pad for commercial vehicles. The Mg composite is reinforced with electroless Ni-P-coated alumina and silicon carbide microparticles using the parameter optimized stir-squeeze method. The particles are coated by using the electroless method and various Mg composites such as Mg alloy, Mg + coated Al2O3, Mg + coated Al2O3, Mg + coated Al2O3, and SiC are prepared. The tribological properties of the newly formulated magnesium composite are premeditated using a tribometer. The brake pad (Mg composite) material is used as a pin, and the disc material (stainless steel) is used as a plate for the experiments. Characterization of the composites is done using a FESEM machine with the attachment of EDAX to measure the elements present in the composite. The results revealed that porosity reduced significantly for the composite which has coated reinforcements. The hardness and compression strength of the composite are also enhanced for the composite which has coated reinforcements. The wear resistance of the prepared Mg composite is closer to other brake pad data, and thus, the material can be used as friction material for automotive brake pad applications.
