Abstract (en)
The present invention relates to a method of making aluminium alloy castings (9) containing an insert (1). This insert is composed of a composite material with metallic matrix, which is constituted by a reinforcement based on ceramic fibres such as fibres of alumina or alumina/silica forming a felt, impregnated under high pressure by an aluminium alloy other than or identical to the cast alloy. In order to achieve the subsequent chemical fixing between the insert and the casting, the surface of the insert is subjected to a chemical treatment of the zincate type, followed by an electrolytic coating treatment. The invention applies to the automobile industry for making aluminium alloy cylinder heads (9) comprising an insert (1) in at least one of its zones (4,5) between valve seats. <IMAGE>
