  • Patent number: 6815400
    Abstract: A method for forming a solid film lubricant on the surface of a part having an arbitrary shape is provided, comprising preparing a carrier having a predetermined shape and size; coating lubricant powder on the carrier; and coating the lubricant powder over the surface of the part by physical contact between the carrier coated with the lubricant powder and the part.
    Type: Grant

  • Publication number: 20020189437
    Abstract: A swash plate of a compressor comprising a plate member supported by a rotation shaft and contacting a shoe supported capable of sliding with respect to a piston, for reciprocating the piston, wherein an intermediary layer is formed on the surface of the plate member, and a solid lubrication layer formed of silver or silver alloy in which an adhesive force to the plate member is strengthened by the intermediary layer. Thus, the swash plate of the compressor according to the present invention exhibits an improved lubrication feature at a high temperature and under heavy load while frictionally contacting the shoe and rotating at a high speed and is prevented from being seizured into the shoe. Also, reliability according to driving of the compressor is improved.

  • Publication number: 20020183209
    Abstract: A method for forming a solid film lubricant on the surface of a part having an arbitrary shape is provided. The method for forming a solid film lubricant includes: preparing a carrier having a predetermined shape and size; coating lubricant powder on the carrier; and coating the lubricant powder over the surface of the part by physical contact between the carrier coated with the lubricant powder and the part. The solid film lubricant has uniform thickness and excellent adhesion regardless of the shape of a target part. Lubrication of the solid film lubricant lasts for a longer period of time without supply of lubricant oil, and under high-load and high-speed operating conditions. Therefore, the solid film lubricant is applicable to a variety of parts widely used in aerospace, defense, and high-precision industries.
