Abstract

PURPOSE: To carry out even etching in a short time, by carrying out electrochemically etching of the inner circumferential surface of a cylinder block made of a high Si-Al alloy.
CONSTITUTION: The inner circumferential surface of a monobloc-cast cylinder block made of a high Si-Al alloy is mirror-finished by honing or the like. Subsequently, an electrolyte is jetted into a uniform gap 1 e.g. between an uprightly standing tool electrode 2 and a cylinder block 4 supported in a hand-standing state, and at the same time, an electric current is sent between the both for several seconds. Thus, only eutectic Al on the inner circumferential surface of the block 4 and which is a good conductor is electrolytically corroded uniformly.
