crystal structures and Friction

darkelf

Hello,

I have this ongoing arguement with my professor. I read in a paper (friction and wear) that the crystal structure can affect friction. HCP crystal structures having lower friction coefficients. I have two papers that mention this in passing one, linking FCC crystal structures to have better plastic deformation but nothing conclusive.

Can anyone shed more light on this? Do HCP crystal structured metals have better friction resistance?

Please cite the paper you read.

I think an examination of the angles between cleavage planes might help.

The first paper would be 'Friction and Wear' Glaeser and the second 'A Simplified Approach to the Adhesive Theory of Friction' Straffelini. They relate it to the plastic deformation properties.
