Abstract:The correct use of lubricant is the key of warm compaction powder metallurgy. Different lubricants produce different lubrication effects and their optimal application temperature will be different. Three different lubricants were used to study the effects of friction coefficient on warm compaction process. Friction coefficients of these lubricants were measured at temperatures ranging from ambient temperature to 200℃. Iron-base samples were prepared using different processing temperatures and their green compact densities were studied.
Key words: warm compaction powder metallurgy; lubricant; friction coefficient
