Graphite contact phenomena developing in interaction with ...

Melts of Al10 wt% Ce, La, Nd, Sm; Al 3 wt% Y; wt% Cu 3 wt% Ti and pure aluminum are used. It is shown that up to 1000 ø C wetting of the graphite surface by aluminum melts of these compositions does not occur, while the wetting angle is established in the first seconds and practically does not change with time.

Wetting of pure aluminium on graphite, SiC and Al2O3 in ...

The wettability of pure aluminium on filter materials and on inclusions is believed to be an important factor affecting the filtration of aluminium. The contact angles of molten aluminium on alumina, SiC and graphite were measured under 10 −8 bar high vacuum in the temperature range of 1000–1300 °C.

Brazing Wikipedia

Brazing is a metaljoining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much ...
