Metal fibre-reinforced aluminium structure - having fibrous core electrochemically roughened to enhance fibre-molten aluminium bonding

摘要

Intended for a bonded matl. of aluminium with reinforcing metallic fibres, the fibre surfaces are electrochemically roughened to give a keyed bond with the cast Al without requiring an inter. bonding layer between the fibres and the Al. In the electrolyte bath catalytic activity is generated, and the surface roughening is effected by oxidn. or redn.
