Experimental analysis of micro-sized particles time-wise adhesion: the influence of impact velocity and surface roughness

•Surface roughness has a greater effect for lower impact velocity values•Sticking laws change over the exposure time according to the detachment process•The detachment process is dependent on the deposited mass and surface roughness Micro-sized solid particle adhesion affects several industrial proc...
