There is disclosed a material wire for wear-resistant and trobologically favorable shaped bodies manufactured by the arc spraying method, which comprises a covering ( ) and a filling ( ). The covering ( ) comprises an alloy based on aluminium with at least one further alloy component, for example magnesium or manganese. The filling ( ) comprises further alloy components for the resulting alloy of the shaped body, for example silicon. The filling ( ) may apart from the silicon also comprise further components, for example aluminium and/or boron. By way of this the composition and the material properties of the resulting alloy of the shaped body may be set.

Arc spraying method

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.
