METAL SOAP-COATED PARTICLE, ARTICLE MADE WITH THE SAME, PROCESS FOR PRODUCTION, LUBRICATING
COATING AGENT, AND LUBRICATING COATING FILM |
(57) Particles each of which consists of an inorganic polyvalent metal compound as a nucleus
and a coating of a metallic soap of the polyvalent metal coating the nucleus (coated
particles); products and preparation processes using the particles; a lubricating
coating forming agent wherein particles each of which consists of a polyvalent metal
salt of phosphoric acid as a nucleus and a coating of a metallic soap of the polyvalent
metal coating the surface of the nucleus are suspended in an aqueous solution of a
water soluble inorganic salt and/or a water soluble organic acid salt; and a lubricating
coating. The coated particles are novel particles which can be used as an ingredient
of coating-type lubricating coating; are excellent in seizure resistance; can inhibit
wear of tools at the time of plastic working since the friction coefficient of the
surface of the particles is low; and are slow to cause pollution of working oils.
Lubricating coating obtained by applying the lubricating coating forming agent onto
the surface of a metallic material gives excellent cold plastic working properties,
namely lubricity and seizure resistance to the metallic material.
