In this paper, a mechanical processing method called MECHANOFUSION was used to investigate the effect of the chamber revolution and core particle size on the composite process. Glass beads were used as core particles, and titanium dioxide was selected as fine particles. The weight fraction of the fine particles fixed onto the core particles surface was measured to characterize the composite process.
As a result, the composite process was described by the following two patterns related to the chamber revolution: Under a critical revolution, fine particles gradually adhered to core particles during the processing time, and at a higher revolution, some portions of the fine particles were detached from the core particles surface after a certain time. Furthermore, the critical revolution was inversely proportional to the core particle size.
These results were explained qualitatively from the analysis of the BET surface area and the SEM pictures of the processed particles.
