The friction coefficient showed a trend of decreasing first and then increasing with the increase in some surface topography parameters at lower pressure, such as the surface height arithmetic mean Sa , surface height distribution kurtosis Sku , surface volume average volume Vvv , and surface center area average void volume Vvc , which are the ISO 25178 international standard parameters.
