Low friction member having seaweed-type nanotubes and method for producing same

A low friction member having seaweed-type nanotubes, comprising:

• a base material;
• a fixing material coated onto the surface of the base material;
• nanotubes which are distributed onto the surface of the base material while being buried in the fixing material and protrude to the outside by means of 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.

A low friction member having seaweed-type nanotubes, comprising:

• a base material;
• a metallic solid lubrication particle which is coated on the surface of the base material;
• and
• nanotubes provided to protrude on the surface of the metallic solid lubrication particle.

A method for producing a low friction member, comprising:

• mixing low thermal expansive glass powder and nanotubes;
• distributing and coating the mixed low thermal expansive glass powder and nanotubes onto the surface of a base material;
• heating and melting, and thereafter, curing the low thermal expansive glass powder covering the surface of the base material to form a fixing material in which the nanotubes are buried;
• surface-processing the fixing material so that the nanotube buried in the vicinity of the surface of the fixing material protrudes;
• and
• coating a liquid lubricant on the surface of the base material.

A method for producing a low friction member, comprising:

• mixing a metallic solid lubrication particle and nanotubes;
• distributing and coating the mixed metallic solid lubrication particle and nanotubes onto the surface of a base material;
• performing heat-treatment while the metallic solid lubrication particle and nanotubes are coated on the surface of the base material;
• and
• surface-processing the surface of the base material.
