Description
Technical Field

Background
Magnetic confinement controlled nuclear fusion is one of the important approaches to solve human energy and environmental problems. With the continuous upgrade of fusion devices, the interaction between plasma and the wall material (first wall) facing the plasma gradually becomes stronger, so that the damage and corrosion of the wall material are aggravated, the operation safety of the fusion device is seriously affected, and the first wall material is one of the bottlenecks restricting the development of controlled fusion.
The first wall of the flowing liquid metal (lithium, tin and lithium-tin alloy) has the advantages of high heat load transport capacity, neutron irradiation damage resistance and the like. By applying the recycling technology of the liquid metal, the problem of the service life of the first wall can be solved, and the problem of recycling of tritium can also be solved. Therefore, the flowing liquid metal can provide a new scientific means for the development of magnetic confinement fusion, has a very good application prospect and is more and more emphasized by the fusion community.
However, through previous experiments, it is found that liquid metal, especially lithium, is difficult to spread uniformly on the surface of stainless steel and liquid lithium is difficult to completely enter a preset stainless steel groove, which indicates that the surface wettability of the liquid lithium to the stainless steel needs to be improved, and the application of the liquid lithium, especially flowing liquid metal, in future fusion devices is greatly limited. Therefore, a series of experimental studies on methods for improving the wettability of liquid lithium are required.
In the early stage, a liquid metal testing platform is developed, a liquid metal ball is titrated to the surface of a testing substrate, and then the shape change of the liquid metal drop is observed in the heating process, so that the wettability of the liquid metal can be measured. However, it has also been found during experiments that the size of liquid metal droplets is difficult to control, especially to achieve titration of micro-droplets (0.5-1mm), experiments typically being carried out using droplets of larger size (>3mm diameter). Due to the gravity influence of the liquid drops, the liquid drops have obvious tendency of falling downwards, so that the measurement of the wetting angle is small, and the wetting property of the liquid metal liquid drops at different temperatures is difficult to accurately reflect.
Because liquid metal, especially liquid metal lithium, has the characteristics of high temperature, easy corrosion and easy oxidation, the precise titration of liquid drops is difficult to realize by adopting the conventional injectors (such as medical injectors) on the market, and a micro-drop (0.5-1mm) injection method required by the high-temperature liquid metal needs to be developed.
