Study of wettability test of pure aluminum against uncoated and …
The wetting angle was observed to be 177°. The wetting of a metal on graphite or diamond surface depends on its ability to form carbide at the interface. Literatures suggest that wetting is usually not observed below 900 °C. In Al–graphite system, a wetting angle of 40° was observed at 1227 °C with formation of Al 4 C 3 at the interface ...

Wetting behavior of aluminium and filtration with Al2O3 and SiC …
This indicates that the improved wetting of aluminium on a filter material is an advantage for molten metal to infiltrate the filter during priming. Also, better wetting of Al-filter might increase the removal efficiency of inclusions during filtration due to better contact between filter and metal. ... Wetting of pure aluminium on graphite ...

The effects of anode dopants and alumina bath content on the wetting properties of the anode/bath interface in an aluminium electrolysis cell have been investigated in this study. Increasing the wettability of the carbon anode maximises the anode surface area and prevents a sudden increase in current density that polarises the anode leading to the discharge of fluoride …
