CRN coating film and sliding member
The present invention addresses the problem of providing a CrN coating film which has excellent peeling resistance such that peeling thereof starting at a crack is unlikely to occur even in a more severe lubrication environment. The problem is solved by a CrN coating film which has a preferred orientation of 200 as determined by XRD, and in which the X-ray diffraction intensity ratio of the (200) plane with respect to the (111) plane, (200)/(111), is 5.5 or higher, and the ratio of crystal grains of 1 μm or smaller is 85% or higher in a crystal grain size distribution measured by an EBSD analysis. |

Preparation method of niobium diselenide film with ultra-low friction and low electrical noise under sliding electrical contact in vacuum
The present disclosure relates to a preparation method of a niobium diselenide (NbSe2) film with ultra-low friction and low electrical noise under sliding electrical contact in vacuum. The method uses a direct current (DC) closed field magnetron sputtering method for preparation. Through process design of low deposition pressure and low sputtering energy, on one hand, a purity of an NbSe2 sputtered product is kept, generation of interference phases such as NbSe3 is avoided, and electrical conductivity of the sputtered NbSe2 film is greatly improved, and on the other hand, a nanocrystalline/amorphous superlattice composite structure is formed, and excellent mechanical and lubricating properties are achieved. Under sliding electrical contact in vacuum, compared with those of a common electroplated gold coating, a friction coefficient of the film is reduced to 0.02 from 0.25, a wear life is prolonged by at least 7 times, and the electrical noise is reduced by about 50%. |
