金属粉末注射成形金属粉末注射成形metal powder injection moulding J .nshu zhushe ehengxlng金属注射成形(metal injeetion moulding) 将金属粉末致密化成复杂形状零件的粉末成形方法。将粒度为。5一2即m的细粉与粘结剂混合均匀，使粉末颗粒被粘结剂均匀包覆，成为具有良好流变性的膏状注射料。注射料在一定温度下，在约10一3OMPa压力下，用注射成形机注入模腔。注射料在模中固结后取出。生坯中的粘结剂用溶剂抽取、热分解或催化缓慢脱除。脱粘后的坯具有35%一55%体积的孔隙，但具有可搬运的强度。注射成形坯在所需要的合适气氛中高温烧结成零件。微细的粉末才能和粘结剂混合成均匀的、具有良好流变性的注射料。微细粉末具有较大的烧结活性，烧结时注射成形坯才能产生显著的均匀收缩。线收缩率达20%左右，获得相对密度大于95写的致密零件。而且是细晶粒显微组织，力学性能达到铸锻材料水平。 粘结剂一般是热塑性树脂，如聚乙烯、聚丙烯和聚苯乙烯等。为改善粘结剂的性能，还需添加增塑剂、润滑剂、稳定剂、软化剂等辅助粘结剂。粘结剂占注射成形坯体积的35%一50%，应缓慢脱除粘结剂。脱粘应力不能大于颗粒间的结合力，否则坯将变形、开裂、破碎。脱粘可在保护气氛中或真空中进行，脱粘时间往往长达十几小时。为改进脱粘过程、缩短脱粘时间，研制了多种类型粘结剂和脱粘方式，如催化脱粘工艺。 注射料在压力下注射填充模腔时处于类流体状态，能成形复杂形状的零件。类流体不可压缩，注射时处于等静应力状态。因此，注射成形坯的密度均匀。烧结时均匀收缩，能精确地保持形状，尺寸公差一般小于士0 .3%。 粉末冶金注射成形适用于低合金钢、不锈钢、工具钢、难熔化合物、硬质合金、金属陶瓷、有色金属及其合金、磁性材料等。从经济合理角度出发，最适于生产大批量(一般不少于数万件)、单重小(0 .5一209)、形状复杂的零件。 自20世纪80年代末以来，金属注射成形应用于工业生产，发展极为迅速。其产品广泛用于民用和军工各领域。 (曹勇家)
