The results show that the originated materials for electrolyte aluminium is Al2O3 and AlF3 has good property to absorb vapour. After the water contained in the originated materials goes into electrolyte, AlF3 reacts with water hydrolyzed and the rest of water is electrolyzed into hydrogen and oxygen. Hydrogen enteres aluminum liquid by diffusing and autoecious in Al2O3, which is the main source of hydrogen in electrolyte aluminum liquid.

Instead, the erosion resistance is increased after FSP. The refined and uniformly distributed second phases, which are resulted from the FSP, can help to increase the hardness and further reduce the brittle fracture of the specimens. Si and nvAl3CuNi phases are usually found near or end of the grooves with little fracture. But the τ1 (Al9FeNi) phase is easier to be removed by the erodent cutting. It can be inferred that Si and nvAl3CuNi are useful to improve the erosion resistance of A384 aluminum alloy, but τ1 (Al9FeNi) phase is detrimental for the erosion resistance of A384 aluminum alloy.
