Metallurgical lubricant powder and metal powder composition

摘要

A powder metallurgy lubricant includes an aromatic carboxylic acid represented by a formula (1),
(Z)n-Ar—COOH  (1)
where Ar represents an aryl group and Z represents a substituent directly bonded to the above aryl group and is one of R, OR, OCOR and COOR, R representing one of an alkyl group, alkenyl group and alkynyl group and n being an integer in a range from 1 to 4. Z may be mutually the same or different when n is 2 or larger.

1. A powder metallurgy lubricant comprising
an aromatic carboxylic acid represented by a formula (1), the aromatic carboxylic acid consisting of carbon, hydrogen and oxygen,
(Z)n-Ar—COOH  (1) where Ar represents an aryl group and Z represents a substituent directly bonded to the aryl group and is one of R, OR, OCOR and COOR, wherein R represents one of an alkyl group, alkenyl group and alkynyl group, and n is an integer of 1 to 4, and when n is 2 or more, plural Z may be the same or different, wherein the powder metallurgy lubricant is in the form of a powder.
