  • Publication number: 20230077757
    Abstract: Problems addressed by the present invention are to provide a lubricant composition that is capable of being used as an alternative to chemical conversion treatment by means of phosphate, to provide a lubricant composition having practical stable lubricative performance without the need for additional unwanted operations, and to provide a method for using this to form a lubrication coating, and a metal workpiece at which a lubrication coating is formed on a surface thereof. Provided as a means for solving such problems is a lubricant composition for causing formation of a hemimorphite-containing lubrication coating that contains a silicate compound (e.g., colloidal silica) and water-soluble zinc in solution.
