AbstractWith an ever increasing variety and complexity of PM parts being produced, many parts producers are looking for a powder feedstock that can allow for high green and sintered densities, improved filling performance, excellent lubricating properties and clean burn-off. Lubricants and other organics used as binders play a key role in responding to all these requirements. Consequently, many efforts have recently been put in the design of proper organic systems to improve the compaction and lubrication behaviour of powder mixes. This paper presents the characteristics of innovative lubricant systems under development with improved lubrication properties compared to the conventional lubricants used in PM. The focus is shared between two development axes: obtaining high green densities and lowering ejection forces. The lubricants were tested at high shear stresses on an industrial press at different compacting pressure and temperatures, which adequately mimics the conditions most parts manufacturers will encounter.
