Abstract
In directly bonding a metal to ceramics, in accordance with the invention, that surface of a metal component which is to be bonded by heating to a ceramic substrate is provided with parallel-running grooves before the preoxidation. The grooves make it possible to optimize the quantity of oxygen available at the bonding location and provide good flow behavior of the melt. As a result, a bond with good adhesion is obtained. Moreover, there is no formation of a thicker oxide layer on the free smooth surface of the metal component.
