“…This phenomenon demonstrates that the weight percent of the CeO 2 nanoparticles embedded into the composite electrodeposits is significantly affected by current density. Many researchers also stated that the embedded nanoparticle content reduced with a rise in the current density [13][14][15].…”

Electroforming has been applied in the fabrication of a mold. However, its lower microhardness has prevented its wider usage in general plastics and optical mold making. In this paper, CeO 2 nanoparticles is first added to the bath to improve the microhardness of the electroformed microprism mold. Compared with microprism pure nickel mold, the microhardness and the wear resistance of the microprism Ni-CeO 2 nanocomposite mold were significantly improved. The maximum microhardness of 530 HV was observed in the nanocomposite deposits obtained at the current density of 1 Adm -2 , and the microhardness of pure nickel is approximately 291 HV. Finally, a microprism Ni-CeO 2 nanocomposite mold was successfully electroformed.

“…Its micro hardness is 902 ± 36 HV 0.1. The deposition of CuSn coatings was performed on Cr coating deposited on cast iron substrates by the electrodeposition technique [33,34]. The CuSn coating on the Cr coating substrate was obtained in a solution containing CuCl 2 ·2H 2 O, SnCl 2 ·2H 2 O and sodium tartrate.…”

In order to investigate the friction and wear behavior between the nodular cast iron cylinder liner (Fe) and CuSn coated piston ring under heavy-duty conditions, piston rings with chromium(Cr) coating and CuSn-Cr coating were tested using the piston ring reciprocating liner test rig at the simulated working conditions of 56 MPa, 200 r/min, 190 • C. Compared with the Cr/Fe pair, the CuSn coating consumption of the CuSn-Cr/Fe pair made friction coefficient and cylinder wear loss decrease by 2.8% and 51.5%, respectively. Different size Sn patches worn from the CuSn coated piston ring were embedded into the cylinder liner surface based on the surface topography. This process was shown to reduce the surface roughness of a cylinder liner and form flatter plateau structures. Chemical elements analysis indicated that plateau structures on the cylinder liner surface matched with CuSn-Cr coated ring are helpful to promote the tribo-chemical reaction and generate the reactive products to protect the mutually contacted asperities.Although surface texturing on the cylinder liner or piston ring is an effective method to improve the wear behavior [7-9], various coatings prepared on the piston rings are also important means to improve heavy-duty friction and wear performance [10]. The CrN coating made by the physical vapor deposition or magnetron sputtering method has shown good high temperature resistance to adhesion [11][12][13][14]. In order to improve the thermal stability, oil compatibility, and internal stress of ceramic coatings, nanocomposite coatings (like TiN, TiAlN, TiSiN and TiSiCN) were developed to minimize the frictional losses and wear of piston rings in an automotive engine [15,16]. Shen et al. compared chromium-based ceramic composite (CKS) and nickel-chromium-molybdenum (NCM) coated rings sliding against cast iron liner and demonstrated that the anti-scuffing behavior of NCM is better than that of the CKS with the failure time as a criterion [17]. Wan et al. indicated that the presence of amorphous graphite-like carbon not only combated the scuffing damage and running instability effectively for conventional chromium-based coatings, but also improved the reliability and robustness of the piston rings [18]. Based on the increasing scuffing resistance experiments, diamond-like carbon (DLC) coated piston ring can protect the cast iron liner from scuffing up to 600 N normal load [19]. Its lower friction coefficient and wear loss were attributed to the formation of a mixed tribolayer [19][20][21]. But the existence of residual stress in the preparation process of DLC coating would cause the coating to crack. If stress concentration exerted on the contact interface was too high, it would lead to the coating wear or peeling [22].Compared with hard coatings, soft coatings have also attracted widespread attention for weakening the friction surface damage. Hamilton et al. investigated the relationship between macroscopic wear and the temperature of the MoS 2 coating [23]. Meng et al. indicated that the stabilized fricti...

“…It has also been reported that the use of PC and even pulse reverse current has led to a higher co-deposition of nanoparticles in the nickel matrix and hence higher corrosion resistance of these composite coatings [10][11][12]. Many parameters such as the electrolyte stirring rate [5], temperature and pH of the electrolyte, current density [13], frequency [14], operating time, type and concentration of nanoparticles in electrolyte [15,16] are involved in deposition properties. Subsequently, change of each of these parameters can affect the thickness, coating structure, surface morphology and the amount of incorporating particles in deposit.…”

Pure Ni and Ni-silicon nitride (Si 3 N 4) nanocomposite coatings have been successfully fabricated on copper substrates by a pulse electrodeposition method employing the Watts bath. The obtained coatings were characterized with X-ray diffractometry and scanning electron microscopy. Also, surface hardness and the corrosion behaviour of the coatings were analysed by potentiodynamic polarization and electrochemical impedance spectroscopy in a 3.5% NaCl solution. It was found that incorporation of Si 3 N 4 particulates has reduced the crystallite size and also changed the growth orientation of the crystallite from (111) to (220) and (200) crystal planes. The co-deposition of Si 3 N 4 in the Ni matrix led to better properties of these coatings. Accordingly, the hardness value of nanocomposite coatings was about 80-140 Hv higher than that of pure nickel due to dispersion-strengthening and matrix grain refining and increased with the enhancement of incorporating Si 3 N 4 particle content. The presence of the Si 3 N 4 particulates slightly decreases the current efficiency. The current efficiency was decreased by increasing current density from 1 to 4 A dm −2. Moreover, the corrosion resistance of nanocomposite coatings was significantly higher than the pure Ni deposit. Also, the Ni-Si 3 N 4 coating produced at a density of 4 A dm −2 showed the lowest corrosion rate (0.05 mpy).
