In this paper, we examined the relationship between surface roughness and particle adhesion behavior bya proposed experiment. Five kinds of SiO2 spherical powders (0.2μm-2.0μm) and stainless steel plateswith seven kinds of surface roughness were used for the investigation. The adhesion ratios of SiO2powders to polished stainless steel plates were measured. The adhesion ratios depend on the surfaceroughness and the particle diameters. The adhered particles on the steel plate were observed by SEM inorder to examine the adhesion mechanism of SiO2 particle on the polished stainless plate substrate. Asthe result, 0.4-1.0 μm particles were easy to adhere independent of surface roughness and nominalpowder diameter. The result indicates that adhesion behavior of powder depends on the adhesion force of0.4-1.0 μm particles that are changed by the surface roughness of the steel plate.
