[0002] Ultra-thin modified coated powder metallurgy refers to a technique in which metal or alloy powder particles are surface-treated to form a very thin (typically nanometer-thick) modified layer or coating layer on their surfaces during the powder metallurgy process. This modified layer can be composed of different materials, such as metal oxides, ceramics, polymers, etc., and can be achieved through various methods, such as atomic layer deposition, chemical vapor deposition, physical vapor deposition, liquid phase coating methods (such as precipitation method, sol-gel method), etc.

[0003] When using liquid phase coating method to surface-treat metal or alloy powder particles, a mixing device is required. However, the existing mixing devices have the problem that the centrifugal force generated during stirring causes a large amount of powder to accumulate on the inner wall of the mixing barrel. The powder in these areas is difficult to reach by the stirring blades, resulting in uneven mixing of the powder and coating material. This insufficient mixing severely affects the coating effect and ultimately affects the overall quality and performance of the product. SUMMARY
