What is it about?

This review examines various fractal models in tribology, focusing on the analytically tractable Cantor–Borodich (CB) profile and its modifications. It highlights that while fractal dimension alone is insufficient to fully describe surface roughness, some models effectively capture its multilevel hierarchical structure, helping to clarify and correct common misconceptions in the field.
