ABSTRACT:
A composite casting is produced by electrodepositing a wear resistance material onto a core, immersing the core in an aluminium melt and then casting an aluminium alloy around the core, before detaching the latter. The wear resistant layer may be given a roughened surface before immersing in the aluminium melt, by increasing the current density in the later stages of the depositing. The method may be used for casting light metal cylinders for internal combustion engines.
