What does the wettability of thermal spray powder mean?

       Wettability is generally mentioned in brazing and rarely mentioned in thermal spraying.

Wetting angle is an index to measure wettability. The English name is wetting angle, which refers to the angle between the liquid-solid interface and the tangent of the liquid surface at the contact point between the liquid phase and the solid phase. When the angle is less than 90°, it means wetting, and if it is greater than 90°, it means no wetting.
