Adhesion(bonding etc.) of materials without frictional force?

Click For Summary
The discussion centers around the relationship between adhesion, bonding, and frictional forces in material physics, particularly in the context of injective moldings. The original poster seeks references to support the claim that adhesion or bonding can only occur with frictional force. Participants in the discussion emphasize that while friction forces play a significant role in adhesion and bonding, there may be instances where bonding occurs without friction. They suggest that numerous academic papers exist that explore specific cases of adhesion and bonding, indicating that a variety of mechanisms can contribute to these processes beyond just friction.

Hello.

I am studying material physics.

I heard in the class that every adhesion or bonding can occur only with frictional force.

Today, I tried to find a proper reference for this statement but I could not.

Is there any reference that every adhesion or bonding(esp. Injective moldings) can occur only with frictional force?

Or is there any way that can happen without frictional force?

Thank you!

It's more that friction forces are adhesion/bonding effects.
What sort of reference do you need? There's no end of papers exploring specific instances for example.
 

Thread 'Need to anneal 5052 aluminum'

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
