润滑剂对Fe基粉末冶金材料温压工艺的影响
Effects of lubricants on the warm compaction process of Fe-based powder metallurgy materials
摘要
Abstract
The effects of zinc stearate,ethylene bis stearamide (EBS),composite lubricant,and compaction temperature on the warm compaction process of Fe-based powder metallurgy (PM) materials were investigated by scanning electron microscopy (SEM) and properties tests.The results show that the apparent density and flow rate of Fe-based powders decrease with increasing lubricant content when the lubricant content is higher than 0.4％,and the effect of EBS is the greatest.The density of Fe-based PM green compacts increases by use of lubricants,and the particles combine more closely when zinc steamte and composite lubricant are used.The effect of lubricants on the green density,sintered density,and bending strength of Fe-based PM samples is composite lubricant ＞ zinc stearate ＞ EBS in order,and the density and mechanical properties of Fe-based PM materials increase with increasing compaction temperature.When the lubricant content is 0.4％,the density of Fe-based PM samples by warm compaction at 120℃ are improved by 0.14～0.21 g/cm3 compared to that of the conventional compaction samples,and the hardness and bending strength are increased by 40％～65％.关键词
