When millimeter- to centimeter-sized particles impact a brittle target at several hundred meters per second in laboratories, the particles are disrupted and craters are formed on the target. Based on these experimental results, it has been assumed that disruption and crater formation also occur during the impact of micrometer sized particles at several hundred meters per second in protoplanetary disks. However, it has been shown in the field of engineering that micron-sized particles can stick to targets even when they collide at several hundred meters per second. In this study, we aim to experimentally investigate whether sticking occurs when micrometer-sized particles of brittle materials and metals collide at several hundred meters per second, and to evaluate the implications of the experimental results for disk evolution.
