Dry friction and wear characteristics of nickel/carbon nanotube electroless composite deposits

Microstructure and mechanical properties of CNT/Ag nanocomposites fabricated by spark plasma sintering

“…The fourth functional group is the C¼C double bond, which was detected by intensive band that appeared at 1625 cm À1 indicates the graphene structure of the CNTs. But, the fifth kind of bonding is the C-H bonding for the CHO aldehyde group by the two bands at wavenumber 2850 cm À1 and 2750 cm À1 [24].…”

Synthesis of multi-walled carbon nanotube/silver nanocomposite powders by chemical reduction in aqueous solution

“…The fourth functional group is the C¼C double bond, which was detected by the intensive band, which appeared at 1625 cm �1 , indicating the graphene structure of the CNTs. But the fifth kind of bonding is the C-H bonding for the CHO aldehyde group by the two bands at wave numbers 2850 and 2750 cm �1 [31] . It is also supported by the X-ray photoelectron spectroscopy (XPS) analysis of the carbon and oxygen, as shown in Figure 3, which is a useful tool to analyse the surface chemistry of CNTs [32].…”

Evaluation of Tribological Properties and Optimization of Electroless Ni-P-W Coating Under Dry Condition Using Grey Fuzzy Analysis

“…The addition of a third element to the binary Ni-P and Ni-B coating leads to the formation of a ternary alloy such as Ni-P-W and Ni-P-Cu [16][17][18][19][20][21][22][23], which again leads to an enhanced wear resistance. Softer particles incorporated with EN coatings such as PTFE, MoS2, graphite and CNTs [24][25][26][27] promote self lubricity and finds their applications in the reduction of friction. The first instance of electroless Ni-P-W coating was reported by Pearlstein and Weightman [28] in 1963 and many investigations were reported henceforth.…”
