Abstract
Surface activation is intended to ensure that a cylinder liner can be anchored in the casting material of a light-metal crankcase with greater bonding. For surface activation, the surface of the cylinder liner is roughened mechanically. Advantageously, copper particles are also implanted into the treated surface. It is necessary to ensure that the time span between surface activation and casting-in is short. Moreover, the activated surface, as far as possible, should not be touched by hand.
