Distribution of surface materials and friction

[pwoh]

I'm trying to search for information relating to friction and a surface with different parts made of different materials.

For example, a plastic box is attached to a wooden box and slid down a track. If we were to switch how the plastic and wood was distributed on the surface, e.g. by swapping the boxes around, would this affect the friction?

I'm trying to find some theory that would relate to this but I'm having trouble finding the right terminology for it. Can anyone help?

Thanks in advanced :D

no. Can you think of ANY possible reason it would?

I can think of some impractical potential situations, but nothing very real.
