FREMGANGSMAATE FOR SAMMENFOEYNING AV EN DEL PAA ALUMINIUMBASIS OG EN STAALDEL VED VARMPRESSING

摘要

The invention concerns a process for assembling aluminum-based members and steel members. This process is characterized by: covering the steel member with a metal film on the part of the surface to be assembled, disposing grains of silicon at the aluminium-steel interface, providing protection from oxidation for the faces to be assembled, heating the members so as to achieve an interface temeperature of from 500 DEG C. to 650 DEG C. and applying a pressure which is sufficient to totally or partially expel the liquid eutectic which is thus formed, cooling the assembly. The assembly which is produced in this way is used in particular in so-called 'clad' connecting members for igneous electrolysis vessels, in armour plating requiring high mechanical strength and in all cases where connections are to be made, which have good electrical and mechanical properties, for continuous use in a temperature range from at least -200 DEG C. to at least +450 DEG C.
