Visualization of the friction process of a Cr.Ni Steel pin running on a disk of similar material under nitrogen has shown that a built-up edge (b.u.e.) is gradually formed and eliminated at contact. The construction of the b.u.e. is described. Metallurgical sections of b.u.e. formed under different conditions are analysed and confirm mechanisms suggested by visualization. Both visualization and b.u.e. examinaton point to the importance of flow transport in friction processes.
