The present invention relates to a low friction member having seaweed-type nanotubes, the nanotubes which protrude like seaweed on the surface of a base material being concentrated in the moving direction of a sliding member, thereby improving the fluidity of a liquid lubricant, thus enabling the effective reduction of surface friction.

Such present invention comprises: a base material which has a plurality of dimples formed on the surface thereof so as to reduce friction occurring due to the surface contact of a sliding member; a fixing material which is filled inside the dimples; nanotubes which are buried in the fixing material and protrude to the outside by means of the surface processing of the fixing material; and a liquid lubricant which is coated on the surface of the base material, wherein, as the protruding nanotubes become concentrated in the moving direction of the sliding member, the fluidity of the liquid lubricant is improved, thereby enabling the effective reduction of surface friction.

Provided are a SmFeN magnetic powder which is superior not only in water resistance and corrosion resistance but also in hot water resistance, and a method of preparing the powder. The present invention relates to a method of preparing a magnetic powder, comprising: plasma-treating a gas; surface-treating a SmFeN magnetic powder with the plasma-treated gas; and forming a coat layer on the surface of the surface-treated SmFeN magnetic powder.
