3 Terms and definitions
The following terms and definitions defined in GB/T 18930 apply to this document.
3.1
Corrosion resistance of molten aluminum alloy
The ability of refractories to resist corrosion and penetration of molten aluminum alloys at high temperatures.
3.2
Erosion surface
The part where the sample reacts with the molten aluminum alloy, which leads to the corrosion, deformation and destruction of the sample section, is shown in Figure 1.
3.3
Permeable surface
The sample reacted with the molten aluminum alloy, resulting in a marked part of the sample infiltrated (including erosion) by the molten aluminum alloy.
see picture 1.
3.4
Original surface
The inner surface of the arc crucible sample in direct contact with the molten aluminum alloy. see picture 1.
