“…The addition of graphite to copper (Cu) leads to a high solid lubricity, and such composites are widely used as brush and bearing materials. 1 In order to improve their frictional and wear properties, copper-based composites containing nanographite, 2 SiC and graphite, 3 TiC and graphite, 4 carbon fibers, [5][6][7][8] carbon onions, 9 and carbon nanotubes (CNTs) [10][11][12] have been investigated. These composites were formed using metallurgical techniques such as microwave sintering and plasma spark sintering.…”

Composite films containing copper and multiwalled carbon nanotubes (MWCNTs) with different dimensions were fabricated by electroless deposition and their microstructure and frictional properties were evaluated. The films were formed using an electroless copper plating bath including dispersants of sodium lauryl sulfate and hydroxypropyl cellulose for MWCNTs. The microstructure of the films was characterized by scanning electron microscopy and X-ray diffraction, and their frictional properties were investigated using a ball-on-disk method without a lubricant. All of the deposited films contained uniformly dispersed MWCNTs, and exhibited significantly lower coefficients of friction than copper films.
