Surface tension of aluminum


2002

Q. I would like to ask what is the surface tension of Aluminum?

Hi Stanley. Sorry, I have no idea what the answer is, but I'd certainly expect it to be temperature dependent. What's the temperature?

Thanks Ted:

What is the surface tension of Aluminum (solid phase with air) at room temperature.

I had no idea that solid metals had the property of 'surface tension'. I guess you'll have to wait for somebody else to answer.

Q. We have a similar question as you showed. My project is to get the surface tension of aluminum/oil system at the room temperature.

According to the Young Equation G(s,v)=G(s,l)+G(l,v)cos(angle), which G express the surface tension. s express the solid,v express the vapor, l express the liquid. the G(l,v),which is the surface tension of oil(liquid and Air) G(s,l) expressed the surface tension of aluminum(solid) and oil(liquid). The G(s,v), which express the surface tension of aluminum(solid) and air. From the equation, the G(l,v) can be obtained from the pendant drop method, Angle can be obtained from sessile method. In order to obtained the G(s,l),the G(s,v) have to first to be known.

So the question I have is what is the G(s,v) at room temperature. If I get it, I can further calculate the surface tension of aluminum/oil.

So the surface tension of the oil is what you are concerned with? And the characteristics of the solid surface in contact with the oil are relatively unimportant?

A. Hey, Stanley Tsai:

The surface energy of crystal aluminum at 300k is 1100 mJ/m^2 under vacuum. Normally, the metal oxide reduces the interfacial energy between aluminum and water. Actually, for the anodized aluminum (alumina),the value of interfacial energy is only 50 mJ/m^2. weidong

Q. But what is the surface energy for liquid aluminum with its vapor?

Q. Why can't we obtain Aluminum-Carbon alloy like Steel?
