Title:
IRON-BASED SINTERED SLIDING MEMBER, AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/021418
Kind Code:
A1
Abstract:
Disclosed are: an iron-based sintered sliding member, in which the precipitation of free cementite in the structure does not occur, and which has excellent sliding properties including friction and abrasion; and a process for producing the sliding member. An alloy powder in an amount of 3 to 20 mass% and a carbon powder in an amount of 1 to 5 mass% are added to and mixed with an iron powder which is the main component to produce a mixed powder, wherein the alloy powder contains 4 to 6 mass% of manganese and 3 to 5 mass% of iron, with the remainder being copper. The mixed powder is filled in a mold to form a compressed powder having a desired shape. The compressed powder is sintered at a temperature of 1000 to 1100˚C for 90 minutes in a heating furnace which has been adjusted to a neutral or reductive atmosphere.
