Friction and wear behavior of electroless Ni-based CNT composite coatings

A study of the tribological behavior of carbon‐nanotube‐reinforced ultrahigh molecular weight polyethylene composites

“…As for the low friction coefficient of the MWCNT/ UHMWPE composite, some authors believe that it is caused by the self-lubrication of CNTs. 10 We used the AFM tip to scratch the composite, but the subsequent examination of the used AFM tip by Raman spectroscopy did not support this explanation.…”

Nanocomposite Coatings: Preparation, Characterization, Properties, and Applications

“…This method is usually applied for producing the nanocomposite coatings with Niken matrix and nanofillers are carbide, nitrite, boride, or PTFE [49,81,82,[111][112][113][114][115][116][117]. In order to improve the hardness, anticorrosion, and antiwear of coating, the thermal posttreatment at 500-700 ∘ C should be applied.…”

“…By embedding nanocrystalline TiC in DLC matrix, Voevodin et al [103,154] obtained the hardness of 32 GPa for this nanocomposite coating. Vepřek et al [155,156] In another direction, in case of Ni-P electroless coatings, incorporation of other nanoparticles, such as CNT [111,112], nano-SiO 2 [113,114], nano-SiC [175,176], nano-WC [115], and nano-Al 2 O 3 [116], increased their hardness. The hardness of all these nanocomposite coatings also increased after thermal posttreatment at 400 ∘ C during 1 h. Similar result was obtained for the thermal sprayed coatings [47].…”

“…In the case of inorganic matrices, for Ni-P electroless coatings, the incorporation of nanoparticles, such as nanoSiO 2 [186], nano-Al 2 O 3 [116,117,187], nano-CeO 2 [188], and CNT [112], increased their anticorrosion in NaCl and H 2 SO 4 solutions. The presence of nanoparticles in Ni-P matrix also reduced their wear rate, as reported for CNT [112], nanoAl 2 O 3 [116], and nano-SiO 2 [113,114].…”

Plasma And Cold Sprayed Aluminum Carbon Nanotube Composites: Quantification Of Nanotube Distribution And Multi-Scale Mechanical Properties

“…There are only few studies on Co-CNT [21], Ni-Fe-P alloy [136] and Ni-Cu-P alloy [135]. Agitation of the bath during processing and ball milling of the CNTs prior to mixing in the bath have been proposed as solution for improved CNT dispersion [120,121,124,128]. The mechanism of deposition in electroless process is based on thermochemistry of the system.…”
