Abstract

This paper analyzed the variation of functional roughness parameters, useful to calculate the real contact area, for nineteen specimens divided in two groups of materials, where nine of them were of SAE 1010 steel and the remainder of SAE 1045 steel. All specimens were subject to plane grinding, using the same process parameters for both materials. The ground surfaces were analyzed in a white light interferometer. The functional roughness parameters were used to calculate the bandwidth parameter, using a routine previously tested for a bearing steel. Based on the statistical variation observed for Sq parameter, the specimens were reclassified in four groups only, which allowed discussing some care required in order to prepare specimens for tribological tests.
