摘要
The invention relates to a process for producing accurately scaled, well-defined surfaces of workpieces made from carbonaceous cast iron and having tribologic properties, more particularly of cylinders or internal combustion engines, said surfaces being subjected to at least two operating cycles consisting of an electrochemical and a subsequent mechanical removal. To obtain a constant surface quality, at least the last operating cycle is carried out in a specified ratio between the electrochemical and the mechanical removal and this is a fixed removal ratio. Preferably, a metal bearing plateau percentage of 40 to 65% of the surface is produced with the last operating cycle.
