纳米复合铝合金XFine

Release date:2018-05-06  source:粉体网  Browse times:444
       复合材料拥有良好的综合性能,在各个领域获得越拉越广泛的应用。英国法布罗(Farnboroagh)航空航天金属复合材料公司新近研发的一种名为xfine的纳米铝基复合材料具有多项优异功能,是用粉末冶金法制造的,其特点是:性能稳定,质量轻,各向同性。以15%~25%纳米级碳化硅粒作为增强材料。这种铝基复合材料的抗力强度高达703N/m㎡,比常规基体铝合金的高50%,接近材的,而且其刚性比钛的高,并有突出的抗疲劳性能。

另外,xfine合金的主要优点之一,是可用常规的钢与硬质合金刀具进行切削加工,而不用金刚石刀具,能以常规刀具进行高速切削,工件表面精细,尺寸偏差精确。其他的优点:抗腐蚀性强;耐磨性突出;摩擦系数小;耐热性高;可用粉末冶金法制造近成品尺寸的零件与锻坯,机械加工特步,还可用于制造零件与挤压各种产品,现在可制造出重达150kg、直径710mm的锻坯。
