“…Table 2 gives the details of the working parameters of the electrodeposition process. The electrolyte solution for the electrodeposition process is prepared as per watts bath standard for Ni coatings [28,29]. During the electrodeposition process, the substrate is connected to negative terminal whereas the Ni is connected to the positive terminal of the rectifier.…”

The tribological behaviour of Ni-based composite coatings on Al6061 substrate with secondary phase hard oxide particles like ZrO 2 , TiO 2 , and Al 2 O 3 at different elevated temperature conditions was compared. The composite coatings with different reinforcement of nano particles were characterized by scanning electron microscopy and X-ray diffraction technique. The higher microhardness value is reported for the Ni coating with TiO 2 particles and Al 2 O 3 particles. At higher temperature limits of 120°C and 140°C Ni-ZrO 2 coatings have found better specific wear rate. The Ni-Al 2 O 3 -TiO 2 -ZrO 2 composite coating fails to achieve better properties due to higher agglomeration of the particles and dendrite growth. The Ni-Al 2 O 3 coating showed steady wear behaviour at different temperature limits. The coefficient of friction values is found nearly similar for all the type coatings at 40°C and 120°C.

“…The corresponding plain uncoated matrix has minimal crystal size in correlation with the nano coated matrix and also the augmentation of the electrodeposited layer is determined by the nucleation and crystal growth phenomenon, which in the case of Ni-Al 2 O 3 /ZrO 2 is on the higher side owing to the Uncoated HSLA ASTM A860 sample exhibits a crystal size of 32 nm, which is calculated from the XRD line broadening [3,21]. The deposition of Ni-Al 2 O 3 /ZrO 2 nano composite reduced the crystallite size to 17 nm (reference to the width broadening and decrease in length of the peak reflecting in figures 9 and 10) [19]. The curtailment in crystalline size also has a variable effect on the residual stress inside the material, which is determined availing the ASTM E2860, sin square Chi technique.…”

“…Similarly, the electrodeposition nano coating is carried out in correlation to thickness, roughness, micro hardness, friction coefficient and wear weight loss of the coated substrate. For addressing multiple attribute problems, researchers have established various decision making algorithms [19] in the lines of ELECTRE, VIKOR, TOPSIS, in which TOPSIS finds its preference to ideal solution with minimal computations by classifying a plane consisting of a common vector solution [20][21][22]. The weighting criteria was carried out by SIMO's method and the TOPSIS tables for ball milling and nanocoating (electrodeposition) are tabulated in tables for which the criteria selection of a common vector plane is highlighted in figure 2.…”

Nano composite coatings on HSLA ASTM A860 alloy, adds to the barrier efficacy by increase in the microhardness, wear and corrosion resistance of the substrate material. Additionally, reduction of delamination of the nano composite coating sample is ascertained. Ball milling is availed to curtail the coating samples (Al2O3/ZrO2) to nano size, for forming a electrodeposited product on the substrate layer. The curtailment in grain size was ascertained to be 17.62% in Ni-Al2O3/ZrO2 nano composite coating. During the deposition process, due to the presence of Al2O3/ZrO2 nano particles an increase in cathode efficiency is ascertained. An XRD analysis of the nano composite coating indicates a curtailment in grain size along with increase in the nucleation sites causing a surge in the growth of nano coating layer. In correlation to uncoated HSLA ASTM A36 alloy sample, a surge in compressive residual stress by 47.14%, reduction of waviness by 32.14% (AFM analysis), upsurge in microhardness by 67.77% is ascertained in Ni-Al2O3/ZrO2 nano composite coating. Furthermore, in nano coated Ni-Al2O3/ZrO2 composite a reduction is observed pertaining to weight loss and friction coefficients by 27.44% and 13% in correlation to plain uncoated alloy respectively. A morphology analysis after nano coating indicates, Ni-Al2O3/ZrO2 particles occupy the areas of micro holes, reducing the wide gaps and crevice points inside the matrix of the substrate, enacting as a physical barrier to upsurge the corrosion resistance by 67.72% in correlation to HSLA ASTM A860 base alloy.

“…These coatings were later discovered to be suitable for wear-resistant applications. In a metal/alloy matrix system, inert ceramic particles of micron to nanoscale are inserted, and electrodeposited composite metal matrix coatings were created [1]. Copper (Cu), aluminum (Al), cobalt (Co), nickel (Ni), chromium (Cr), and other graphene-enhanced metal matrix composite coatings are currently being electrodeposited.…”

Corrosion resistance across a wide temperature range, increased physical, mechanical, and tribological capabilities, variable surface hydrophobicity, and an attractive appearance are all advantages of electrodeposited metal matrix composite coatings (MMCs). As a result, several studies have been conducted to evaluate the various physical, mechanical, biochemical, electrochemistry, and thermodynamics characteristics of nanocrystalline composite material, generated on a variety of substrates with numerous electrodeposition settings. In this review paper, the current literatures on wear rate of electrode-posited Ni-based coatings made of composite materials are being reviewed. More specifically, the research papers on weight management, wear resistance, coefficient of friction, surface roughness, hardness and associated deterioration methods has been identified and reviewed. The observations showed that nano-composite films offer substantially superior wear resistance than magnesium alloys and pure nickel coatings due to the diffraction stiffening and grain refining effects. Also, abrasion is the main wear process for nano-composite coatings, whereas adhesion wear is the primary wear arrangement for magnesium alloys and major wear mechanism for pure nickel coatings is exfoliation wear.
