Investigation of Structure and Physico-Mechanical Properties of Composite Materials Based on Copper - Carbon Nanoparticles Powder Systems

Abstract: BADANIE STRUKTURY I WŁAŚCIWOŚCI FIZYKO-MECHANICZNYCH SPIEKANYCH MATERIAŁÓW KOMPOZYTOWYCH MIEDŹ-NANOCZĄSTKI WĘGLAPhysico-mechanical and structural properties of electrocontact sintered copper matrix-carbon nanoparticles composite powder materials are presented. Scanning electron microscopy revealed the influence of preliminary mechanical activation of the powder system on distribution of carbon nanoparticles in the metal matrix. Mechanical activation ensures mechanical bonding of nanoparticles to the surface of… Show more

“…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. 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].…”

“…One of the main directions of modern materials science development is a development of selflubricating coverings on the base of metal matrix permitting to solve successfully the problems of ensuring the critical friction units by complex of required characteristics: operate reliability, high wear-resistance, stability of work, etc. [1]. The promising direction of obtaining the composites of antifriction purpose in dry friction units is the introduction of carbon having high tribological and physic-mechanical characteristics into metal matrix [2].…”
