递压力。当往粉末中加入液体润滑剂(如甘油等)时,对减少颗粒间的摩擦有良好的效果,对压制有利。旋转时,压坯内侧与外侧所受的离心力不同,与离心力相反的方向越长,其效果越小。离心力同质量成正比,所以密度大的粉末比密度小的粉末致密效果显著。另外,断面直径小于郁mm的制品不宜采用此法。 (张齐勋)1 ixin ehengxing离心成形(eentrifugal eompaeting)借助于离心力作用使粉末成形的方法。它不需要压力机和模冲,是将粉装入模具并安装在高速旋转器上,让离心力直接作用在各个粉体上,使它致密化并得到密度较均匀的坯块。该法用来制造普通压力机难以成形的特殊零件。 利用离心力成形虽属单向加压,但比普通钢模压制的压坯密度均匀,并且在形状复杂时也能很好地传
