Аннотация

The formation and properties of coatings produced by electrodeposition on a cathode on the basis of an amine-containing oligomeric film-forming⇌ent modified with highly dispersed polytetrafluoroethylene, polyphenylene sulfide, and fluorine rubber were studied. A procedure is suggested for introduction of powdered polyphenylene sulfide into a formulation for cathodic electrodeposition. It was found that polyphenylene sulfide and polytetrafluoroethylene form a separate phase in a coating; during electrodeposition on a cathode, fluorine rubber SKF-264B enters into a chemical interaction with the amine-containing oligomeric film-forming agent; a scheme of this interaction is suggested. A formulation was created with a triple modification of the amine-containing oligomeric film-forming agent with polytetrafluoroethylene, polyphenylene sulfide, and fluorine rubber. This formulation forms a wear-resistant coating with increased chemical and corrosion resistance.
