TY - JOUR AU - Persson, Bo TI - On the Use of Surface Roughness Parameters JO - Tribology letters VL - 71 IS - 2 SN - 1023-8883 CY - Dordrecht PB - Springer Science Business Media B.V. M1 - FZJ-2023-03426 SP - 29 PY - 2023 AB - In most practical applications, surface roughness is characterized by just one or two parameters (numbers). I show that the standard maximum surface height parameters fluctuate strongly between different surface realizations (or measurements), and should not be used in the design of engineering components. I show how some roughness parameters depend on the size of the roll-off region in the surface roughness power spectra, and introduce a new height parameter which is very reproducible. The numerical results presented agree well with experimental observations.
