PROCEDURE FOR INCREASING RESOURCE AND RELIABILITY OF MAGNET-LIQUID DEVICES Russian patent published in 2011 - IPC H01F3/10 H01F41/00 

FIELD: machine building.

SUBSTANCE: procedure consists in processing surface of magnet-conducting parts of magnet-liquid device contacting nano-dispersed magnetic liquid by mechanic or galvanic method to reduce height and roughness asperity spacing, in application of protective layer out of non-magnetic material of thickness Δ=n×R_z, where n≥0.3 is coefficient of proportionality, while R_z, mcm is roughness height of profile of rough surface, whereto non-magnetic coating is applied; further, magnetic field is generated in device and there is introduced nano-dispersed magnetic liquid.

EFFECT: elimination of negative effect of near surface re-distribution of magnetic field strength onto magnetic liquid and increased reliability and resource of known magnetic-liquid devices.
