粉末冶金复合粉末冶金复合powder metallurgical bonding fenmo yelin fuhe粉末冶金复合(powder metallurgieal bona-ing)各种粉末(金属、合金或陶瓷粉末)之间或各种粉末与实体金属材料之间，靠粉末的烧结并进行加压成形，制作双层或多层复合材的工艺。烧结是通过扩散、蒸发和凝聚、枯性和塑性流动等过程使粉末压坯的粉末颗粒粘结以及孔隙球化、收缩和封闭。因此在粉末冶金复合中升温和加压都会促进粉末复合。若存在适量的液相组分复合更容易进行。 一般有热粉末加压复合成形和冷粉末加压复合成形两种工艺。前者是烧结和加压成形同时进行;后者是成形后进行烧结。有的以热粉末在糊状金属熔体中加压成形，也有的把粉末散布在实体金属上加压成形。 粉末冶金复合工艺的应用范围是:(1)复合组元中有不能发生塑性变形的脆性材料或用熔铸法难以形成合金的材料，可先制成粉末，采用粉末冶金复合工艺制成粉末冶金复合材;(2)许多耐磨材料和多孔材料等是优良的粉末冶金制品，但其强度低，若把这些材料的粉末与强度较高的实体金属材料复合，则可得到性能优异的复合材;(3)可以采用轧制、锻造和挤压等金属塑性加工方法来实现加压复合成形。 以金属粉末为原料的粉末轧制法是生产双层或多层金属复合带材的常用方法，分垂直轧法(图a)和水平轧法(图b)。垂直轧法是在供料漏斗中放置一个或多个隔板，而把各粉末装入各自的空腔中从垂直方向喂入轧辊进行多层粉末轧制;水平轧法是用一个或多个供料漏斗从每个漏斗中漏下的不同粉末散布在实体金属带上从水平方向喂入轧辊进行多层粉末轧制。、 奥墨 星号=砌瞥 b 双层和多层金属带的粉末轧制示意图 a一垂直轧法;西一水平轧法用加热的实体金属带或线从盛于供料漏斗中的其他金属粉末中穿过，粉末覆在带或线上然后进行轧制或连续挤压，可以生产强化复合的带材或线材。例如把用高频电流加热到600℃的钢丝直接送入盛有铝粉的供料斗时能把其周围的铝粉预加热到400℃左右，然后钢丝载着预热的铝粉一起被轧辊咬入进行轧制复合，接着再进行两道致密化精轧可轧出银芯强化铝导线。 影响粉末冶金复合的主要因素有粉末的形状和位度、烧结的温度和时间、加压变形量、变形温度、变形速度以及加压变形后的热处理等。 用粉末冶金复合法制出的双层金属和多层金属有钢一铝、铁一铜、铁一镍、镍一钥、铜一铁一铜、镍一铁一镍、铁一不锈钢、钦一不锈钢、纤维或颗粒强化复合材料以及金属与陶瓷等特殊用途的复合材料。这些复合材料日益广泛地应用于各种工业部门。
