A process for producing a metal-coated, metallized substrate made of one of aluminum nitride ceramic and metal substrate so obtained

摘要

the invention concerns a method of producing a metallized substrate metallbeschichteten, from aluminiumnitridkeramik in steps: $a - preparation of a metallisierungspaste,containing a powdery glass of - al2o3 - sio2 mno system and a refraktu00e4rmetallpulver, $a - application of metallisierungspaste on the substrate surface.$a - out of metallisierungspaste coated substrate at a temperature 1100u00b0c reduced feuchtgasatmosphu00e4re from wasserstoffhaltigem nitrogen$a - lesotho of metallized substrate by plating, $a is characterised by the.during the heating process which metallisierungspaste coated ceramic substrate of the atmosphere with water vapor that is moistened.that the water vapour content in the temperaturintervall between c / s and 1050u00b0c a dew point of 295 k and the water vapour content is outside the temperaturintervalls a dew point 295 kthe invention relates to a corresponding $also metallbeschichtetes metallized substrate from aluminiumnitrid.
