METHOD OF OBTAINING POLYMERIC ANTIFRICTION COATING Russian patent published in 2006 - IPC C09D127/12 

FIELD: polymer materials.

SUBSTANCE: invention relates to making polymeric antifriction coatings, which are applied onto solid surfaces in order to lower coefficient of friction and thereby reduce wear of contact surfaces in friction units. Invention discloses a method of obtaining polymeric antifriction coating on the surface of an object comprising consecutively cleansing this surface with cleansing agent, drying cleansed surface, applying antifriction composition, notably solution of organofluorine surfactant: perfluoropolyoxyalkylene or perfluorinated derivative of poly(alkylene oxide), by immersing the object into this solution followed by heat treatment of coating. Cleansing and drying of the surface are effected in a first vessel, cleansing being performed by immersing the object into vessel with cleansing agent under effect of ultrasound and drying being conducted under effect of infrared rays. Application of antifriction composition and heat treatment are effected in a second vessel, antifriction composition being applied be immersing object into vessel with antifriction composition at 50-60°C affect by ultrasound with frequency 18-22 kHz and heat treatment being conducted with the aid of infrared emitter.

EFFECT: enabled formation of antifriction coating exhibiting needed wear resistance and protecting surface of object against destruction under considerable loading and high temperature conditions.
