Synthesis of functionally graded nano Al2O3–Ni composite coating by pulse electrodeposition

Tribological and electrochemical corrosion behavior of Ni–W/BN (hexagonal) nano-composite coatings

“…The performance of the composite materials mostly depends upon the co-deposition of second phase nanoparticles and their homogeneous distribution in metal medium [10]. Pulse current electrodeposited composite coatings have possessed higher particle incorporations and enhance corrosion resistance and tribological properties compared to direct current electrodeposits [11,12]. The Ni/BN composite coating has revealed superior hardness and wear resistant properties as compared to pure Ni [13,14].…”

Ni–Fe–Mn–(nano)Al2O3 Coating with Modulated Composition and Grain Size

“…3b. The long off-time at low duty cycle gives more time for the alumina particles to arrive at the double layer [24]. As a result, more alumina particles can be incorporated at lower duty cycle.…”

“…Another reason for higher amount of embedded alumina nanoparticles in the coatings with decreasing duty cycle is the increase in the i avg from 0.8 A/dm 2 for the 20 % duty cycle to 3.6 A/dm 2 for the 90 % one. At high i avg , the particles are likely to be incorporated in the layer due to limited mass transport conditions [24]. The increase in pulse frequency for the VD samples leads to the enhancement of the alumina nanoparticles content in the matrix.…”

Investigation on the evolution of microstructure and texture of electroplated Ni–Ti composite coating by Rietveld method

“…The electroplated Ni matrix composite coatings have been developed for a wide variety of practical applicatons over the last twenty years [2,3]. Typically, micrometer and submicrometer particulates of metals, oxides, carbides and nitrides have been codeposited with Ni electroplates [4][5][6][7]. The particulate inclusions impart Ni matrix composite coating with plenty of desired properties ranging from enhanced mechanical property to anti-corrosion behavior [1,[8][9][10].…”
