Processing of copper–carbon nanotube composites by vacuum hot pressing technique

Microstructure and mechanical properties of spark plasma sintered titanium‐added copper/reduced graphene oxide composites

“…Here, the Brinell hardness value for 6-titanium composite reaches the maximum (HB 79.1) and increases by 70.1 %, relative to no titanium-added composite (HB 46.5). Such hardness value is higher than the sintered carbon nanotube/copper (~HB53.0 [22]) and alumi-nium oxide/copper composites (7.5 wt.% aluminium oxide nano-particle: HB67.9 [23]). An increase in the hardness of copper matrix from graphene addition was confirmed [8].…”

Ternary Cu–CNT–AlN composite coatings consolidated by cold spray deposition of mechanically alloyed powders

“…3 other particles (e.g., ceramics or other metals) become dispersed and embedded in the matrix [20][21][22]. On the other hand, the CGDS technique is a solid-state deposition technique that uses a relatively low-temperature pressurized carrier gas and a converging-diverging or De Laval nozzle to accelerate powder particles to supersonic velocities prior to impact [16].…”

The influence of carbon (fullerite, graphite) on mechanical alloying of Cu-25 at % C composites

“…In most cases, graphite can be utilized [1,[5][6][7][8]. Nanotubes [9][10][11][12][13], nanodiamonds [2,5], and fullerites [3,[14][15][16] are mentioned in the literature as possible carbon sources.…”

“…Nanotubes [9][10][11][12][13], nanodiamonds [2,5], and fullerites [3,[14][15][16] are mentioned in the literature as possible carbon sources. Among the methods used for modification of copper with carbon are sintering [6,13], the formation of film coatings by the joint deposition of Cu and carbon [15,16], carbon deposition from gaseous phase via the catalytic decomposition of acetylene and ethylene with subsequent compacting and sintering [12], application of ultrahigh strain [1], and shock-wave loading [14]. Also, a promising technique is mechanical milling in high-energy ball mills [2,[3][4][5]7].…”
