“…There are several works in the literature in which MMC functional coatings are produced to improve the mechanical properties of the substrate. Some of them are presented here [37,38,40,47,75] as an example, because this item alone could be the topic of another review chapter. The generally studied electrodeposition parameters, such as stirring speed or current density, are still mentioned [47,75].…”

The deterioration of materials, particularly metals, under the influence of electrochemical corrosion is a high cost problem faced by nearly all industries. The reduction of corrosion processes and the prevention of future problems require a detailed knowledge of these processes and of the strategies to avoid them. In this context, it is essential to use methodologies that may prevent the electrochemical deterioration of materials as well as monitor their performance in aggressive environments. Among them, it is possible to cite the use of functional coatings, particularly nanocomposite coatings. Therefore, this chapter proposes a review concerning the production of nanocomposite coatings with anticorrosive application obtained by electrodeposition technique (electrochemical codeposition). The production of such coatings is in agreement with the current needs of innovation, which drives a requirement for scientific advancement and the need for fundamental research. In this context, nanocomposite coatings with anticorrosive properties promote changes in metal surfaces, creating new materials with improved characteristics compared to those originally observed and maintaining the integrity of these surfaces.

“…), (3) co-depositing TiN, SiC and other ceramics nano particles. The nucleation and growth of matrix metal grain during process of crystal may be controlled by applying pulse electrodepositing method, smaller grain size and more dense structure of depositing coating may also be gained [1][2][3]. Moreover, the physical and chemical properties of coatings can be improved, the excellent performance of the coating can be obtained, and the precious metals can be saved by changing the parameters of pulse current [4][5][6].…”

Abstract. Ni-nanoTiN composite coatings were electrode posited on 45 steel substrate by using the ultrasonic-electrode position for nickel sulfamate bath. The effects of direct current, positive pulse current, reverse (positive and negative) pulse on surface morphology, binding force, micro hardness, friction and wear performance of Ni-nanoTiN composite coating. The results show that the micro hardness is 322.68 HV 0.1 , the critical load of binding force is 25N, bigger cracks, rough surface, coarse grains and bad wearing of coating when direct current deposition; the micro hardness is 371.74 HV 0.1 , the critical load of binding force is 40N, smaller cracks, smooth surface, relatively small grain, better friction and wear performance of coating when positive current deposition; the micro hardness is 494.18 HV 0.1 , the critical load of binding force is over 50N, non cracks, more smooth surface, tiny grains, best friction and wear performance of coating when positive and negative pulse deposition. Positive and negative pulse deposition may further refine grain, improve surface morphology, increase nanoTiN particles co-deposition and enhance mechanical properties of composite coating.

“…Electrodeposited Ni matrix composite coatings have been widely studied and used because of their advantages of easy maintainability, low cost and excellent properties including mechanical, tribological and anti-corrosion property [8][9][10][11]. And the properties of Ni coatings are strongly influenced by the microstructure of Ni matrix.…”

“…Various kinds of oxides, carbides and nitrides particles have been utilized to prepare the electrodeposited Ni matrix composite coatings. The second phase particles, including Al 2 O 3 [27], TiO 2 [8,10], ZrO 2 [12], Y 2 O 3 [28], CeO 2 [21], SiC [9,11,19,20,25], TiC [22], WC [23,24], AlN [26], Si 3 N 4 [29], TiN [30] and BN [31] etc, have been incorporated into the Ni matrix composites by electrodeposition. Previously, we have electrodeposited Ni-ZrC composite coatings and found the composites exhibited higher hardness and anti-corrosion than pure Ni coating [32].…”
