Title:
LUBRICANT FOR METAL-POWDER METALLURGY, METHOD FOR MANUFACTURING SAID LUBRICANT, METAL POWDER COMPOSITION, AND METHOD FOR MANUFACTURING METAL POWDER METALLURGY PRODUCT
Document Type and Number:
WIPO Patent Application WO/2014/123106
Kind Code:
A1
Abstract:
This lubricant for metal-powder metallurgy comprises particulate bodies containing at least one amide compound selected from the group consisting of the amide compound expressed in general formula (1), and the amide compound expressed in general formula (2), particles having a diameter larger than 198 µm constituting less than 1% by mass, and particles having a diameter of 10 µm or greater constituting no more than 10% by mass. This lubricant for metal-powder metallurgy achieves a low rattler value at low density without inhibiting lubricity, and can provide green bodies and sintered bodies without cracking, chipping, or density imbalance. In formula (1), R
1 and R
2 independently represent C13-27 aliphatic hydrocarbon groups, and m represents a number from 1 to 6. In formula (2), R
3 represents a C13-27 aliphatic hydrocarbon group.
