Overview
The liquid phase aluminum and solid phase material wetting angle tester is suitable for measuring the wetting angle of aluminum liquid and solid phase materials. $r $n aluminum forms a dense oxide film on its surface at room temperature, so it is impossible to perform accurate measurements by placing the sample in advance. This device adopts the method of instant dripping under high vacuum conditions, and the fresh aluminum liquid without oxide film falls on the solid material test piece. The testing process is under high vacuum protection, so that the correct measurement results can be obtained.

Wetting angle tester for liquid phase aluminum and solid phase materialsIntroduction
Wetting angle tester for liquid phase aluminum and solid phase materialsSuitable for measuring the wetting angle between liquid phase aluminum and solid phase materials.
When measuring the wetting angle between liquid-phase aluminum and solid-phase materials, surface oxidation of the aluminum liquid is the main factor affecting measurement accuracy.Aluminum is highly prone to oxidation, forming a dense oxide film on its surface at room temperature. Due to the oxide film blocking direct contact between aluminum liquid and solid materials, accurate measurement results cannot be obtained. So,Overcoming the surface oxidation of liquid aluminum is the key to accurately measuring the wetting angle between liquid aluminum and solid materials.
Wetting angle tester for liquid phase aluminum and solid phase materialsProvide testers with1×10－4PaThe high vacuum testing environment,Make the metal melt not form an oxide film even at high temperatures.
When measuring the wetting angle between liquid-phase aluminum and solid-phase materials, it is not possible toAdopting the method of pre placing samples, becauseAluminum metal forms an oxide film on its surface at room temperature, making it impossible to obtain fresh droplets without an oxide film and perform accurate measurements. This device adopts the method of instant dripping of aluminum liquid under high vacuum conditions, that is, aluminum melts in the vacuum furnace, and during measurement, one droplet of aluminum liquid is dropped through the droplet control device, so that the droplet falls onSolid phase material test pieceAbove isFresh aluminum liquid without oxide film, and the testing process is under high vacuum protection, so as to obtainCorrect measurement results.
Wetting angle tester for liquid phase aluminum and solid phase materialsIt mainly consists of a high vacuum testing furnace, vacuum detection equipment, droplet control device, gas protection system, and computer image acquisition and processing system. The main technical parameters are as follows:
Operating Temperature800℃～1600℃optional
System vacuum degree:1×10－4Pa
Measurement range:0-180°
