Claim 1:
2. The evaluation method of mixing uniformity of composite powder according to claim 1, wherein a specific process of determining flow energy of each standard composite powder in S3 and determining flow energy of the composite powder to be evaluated in S5 includes the following steps:
S3a, placing the composite powder to be determined in a container of a powder analyzer and cutting it to obtain volume-fixed composite powder to be determined;
S3b, placing a propeller rotating deeply from a surface layer of the volume-fixed composite powder to be determined, recording a height H of the propeller entering the composite powder to be determined in real time, and determining flow energy TFEH of the composite powder to be determined at corresponding height, wherein the propeller rotates anticlockwise at an angle of +5 to 10°, and a speed of the propeller is 5-100 mm/s;
S3c, calculating the flow energy ∫0H(TFEH)dH of the composite powder to be determined.
