  • Cylinder liner for combustion engines and manufacturing method
    Patent number: 6354259
    Abstract: A method for the manufacture of a cylinder liner for combustion engines and a cylinder liner which can be manufactured by the method according to the invention are disclosed. The method comprises a thermal spray-deposition, such as by an arc spray-deposition process, of a wearing layer on a supporting body and a spray-deposition of a protective or connecting layer on the wearing layer. The wearing layer comprises a hypereutectic aluminum-silicon alloy and the protective or connecting layer comprises a hypoeutectic aluminum-silicon alloy. A melt retarder of iron, for example, may be interposed between these two layers. The melt retarder comprises a higher melting temperature than the two aluminum-silicon alloys, thereby preventing the wearing layer from partially melting when the cylinder liner is cast into a cylinder bore.
