Abstract: Various surface textures, characterised in terms of roughness parameters using an optical profilometer, were produced on the steel plates. Sliding experiments were conducted on the prepared hard steel plate using a soft Al-Mg alloy pin under both dry and lubricated conditions. The contact surfaces were examined using SEM to study the transfer layer formation on the plate surface and damage on the pin surface. Results showed that among the surface roughness parameters, the coefficient of friction and transfer layer formation are strongly controlled by a roughness parameter, namely mean slope of the profile, Δa, regardless of the surface textures.
