摘要
从铁粉类型、粒度组成、化学成分和粉末显微硬度等因素对温压生坯密度的影响情况进行了系统试验 ,结果表明 ,通过控制粉末形状、粒度分布、化学成分等因素 ,温压可获得高压坯密度 ,在本试验中 ,经过处理的国产粉温压压制密度最高可达 7.30g/cm3,接近国外粉末压制密度。
This paper gives a research of the influence of characteristics of iron powders on warm-compacted density.The result shows that high green density can be abtained in warm compaction process by controlling iron powder types,particle distribution, chemical content and powder micro-hardness.Following the present research results,domestic iron powder can warmly be compacted up to the density of 7.30 g/cm 3.
