Explosive Behavior During Binary-Droplet Impact on Superheated Substrates

•Impact of bicomponent droplets on superheated substrates studied experimentally.•Contact boiling, transition boiling, and Leidenfrost levitation regimes observed.•Scaling analysis for stable dynamic Leidenfrost state post-impact presented.•New explosive boiling regime found within temperature and concentration ranges.•Possible explanation for the existence of the explosive boiling regime proposed.
