补充资料:机械工程材料:粉末冶金多孔材料
用粉末冶金的方法製造的﹑内部结构为多孔的材料(或製品)﹐一般由球状或不规则形状的金属或合金粉末经成形和烧结製成﹐又称烧结多孔材料。这种材料为孔道纵横交错﹑互相贯通的多孔体﹐通常具有30~60%体积的孔隙度﹐孔径1~100微米。常用的金属或合金有青铜﹑不锈钢﹑铁﹑镍﹑鈦﹑钨﹑鉬以及难熔金属化合物等。做成的製品有坩堝状﹑碟状﹑管状﹑板状﹑薄膜等。粉末冶金多孔材料的特点是﹕孔径和孔隙度均可控制﹔优良的透过性能﹐且在使用后可以再生﹐因而使用寿命长﹔导热﹑导电﹔耐高温﹑耐低温﹑抗热震﹔抗介质腐蚀﹔比表面积大﹔可焊接和加工等。因此它的综合性能较传统的纸质﹑棉和化纤织品﹑陶瓷﹑玻璃﹑金属丝网等过滤材料为好。在现代技术中﹐多孔材料愈益发挥其重要作用﹐有两方面的主要用途。作过滤器用﹕利用其多孔的过滤分离作用净化液体和气体。例如用来净化飞机和汽车上的燃料油和空气﹔化学工业上各种液体和气体的过滤﹔原子能工业上排出气体中放射性微粒的过滤等。利用其孔隙的作用﹐製造多孔电极﹑灭火装置﹑防冻装置﹑耐高温喷嘴等。多孔电极主要在电化学方面应用。灭火装置是利用其抗流作用而防止爆炸﹐如气焊用的火焰防爆器等。防冻装置是利用其多孔可通入预热空气或特殊液体﹐用来防止机翼和尾翼结冰。耐高温喷嘴则是利用表面发汗而使热表面冷却的原理﹐被称为发汗材料。(见彩图 粉末冶金多孔材料 )
