Theoretical Analysis of Powder Size Distribution
Abstract
The procedure conventionally employed to interpret the experimental sieving data was examined. It was demonstrated that the conventional procedure is inherently flawed in several aspects. Along with several implicit, hard-to-be-justified assumptions associated with it, the conventional graphical representation procedure also failed to address the reliability of the results. To resolve these problems, a new procedure was formulated. Application of the formulated procedure to several sets of sample sieving data reveals that it is capable of extracting the total weight of powders from experimental data, of determining the nature of the size distribution, of establishing the characteristic parameters, and simultaneously, of determining the reliability of the results. It is anticipated that the accomplishment achieved in the present study will generate significant impact on the understanding and the development of powder related processing technologies, including conventional powder metallurgy, conventional spray atomization, and novel spray processing techniques such as spray atomization and deposition, plasma spray forming, and thermal spray forming.
