Carbon nanotube has special physicochemical and mechanical property with the coaxial carbon tube nanostructure of its uniqueness.The intensity of carbon nanotube is 100 times of guiding principle, can be used for preparing advanced matrix material.Carbon nanotube has certain self-lubricating property simultaneously.Therefore carbon nanotube can improve the tribological property of matrix material and composite deposite.Document [1] has been introduced a kind of Ni-P composite deposite that contains carbon nanotube, and its wear rate has only 1/6～1/5 of Ni-P chemical plating, and frictional coefficient is reduced to 0.06 by 0.10～0.11 of Ni-P chemical plating.
The transient metal sulfide (as: moly-sulfide) of tradition laminate structure has obtained using widely as lubricant, but because the undersaturated dangling bonds of its crystal edge have chemically reactive, in friction process, be adhered to metallic surface and oxidized easily, tribological property is sharply reduced.Recently, the synthetic and applied research of transient metal sulfide (as: moly-sulfide) nanotube has obtained paying attention to widely.Because the moly-sulfide nanotube has the co-axial nano tubular structure that is similar to carbon nanotube, therefore will have good Tribological Applications.But the synthetic relatively difficulty of this transient metal sulfide (as: moly-sulfide) nanotube, the synthetic amount is also fewer.Document [2] has been introduced a kind of hydrothermal synthesis method of composite nano tube of molybdenumdisulphide enveloped carbon nanometer tube recently, and the preparation of this carbon/molybdenumdisulphide composite nano tube is to be template with the carbon nanotube, is molybdenum source and sulphur source with molybdate and thiocarbamide.Document [3] has been introduced by be adsorbed on the surface of carbon nanotube with ammonium thiomolybdate, and thermal degradation can prepare carbon/molybdenumdisulphide composite nano tube then.This carbon/molybdenumdisulphide composite nano tube is to have coated 2～6 layers coaxial moly-sulfide nanotube on the surface of carbon nanotube, and the overwhelming majority has coated 3～4 layers coaxial moly-sulfide nanotube.This compound carbon/molybdenum disulfide nano tube combines the superpower mechanical property and the good self-lubricating property of moly-sulfide nanotube of carbon nanotube, therefore, will have good Tribological Applications in matrix material and composite deposite.
But yet there are no report about the research that has the composite deposite of high-wear resistance and self-lubricating with carbon/molybdenumdisulphide composite nano tube preparation up to now.
