L] for test liquids and cosines of wetting angle on surfaces, we can construct a plane in the coordinates ([square root of ([[gamma].
Generally, the surface condition of the sphere, for example, static wetting angle, can dramatically affect the water entry phenomenon.
After the alloy block was melted again in a vacuum high frequency induction furnace at 700[degrees]C for 30 minutes and cooled down, the wetting angle between the alloy and the ceramic matrix was measured.
It has been found if adhesive angle is less than 90 degrees wood surface has good wetting--the lower wetting angle leads to better wetting.
Regardless of the method used, any contact angle less than 90[degrees] represents a wettable/hydrophilic surface, while a hydrophobic surface wetting angle is greater than 90[degrees] (see Figure 1).
Limiting wetting angle of batch material compacted under a pressure of 20 MPa ([empty set] 12, height: 4 mm) was determined from the profile of water droplets thereon (Voyutsky, 1964).
It has also been observed that the emission of drops depends to a great extent on the static wetting angle, that is, the angle that the drop makes with the contact surface.
Abstract: This paper presents some wetting angle calculation methods.

Figure 3b shows the wetting force as a function of the wetting angle after 2 seconds.
Its hydrophobic properties are especially evident at a wetting angle up to 120x.
After completion of joints, samples have been cut for the analysis of solder wetting angle.
