N2 - Evaporation of water droplet can be enhanced by plasma irradiation that increases the surface wettability. Relation between plasma irradiation time and contact angle was examined first of three metals and then the lifetime of water drop on hot surface was measured changing the surface wettability by plasma irradiation. The lifetime of water drop decreased and the wetting limit temperature increased with the increasing irradiation time of plasma. Hydrophilicity by plasma irradiation is not a permanent effect but it will be useful for enhancement of cooling of hot metal.
