摘要
Tungsten layered alumina composite is being extensively used in electronic packaging. In the present work alumina substrate densification and adhesion aspects between substrates and tungsten overlays are investigated. The effects of sintering atmosphere, temperature, lubricant content, metal binders treatment and their amount on adhesion behaviour and transverse rupture strength have been reported. SEM studies have also been supplemented to correlate the structure property behaviour. (C) 1998 Elsevier Science Ltd. All rights reserved.
