The present disclosure refers to a partial texturization applied on a contact interface of a scroll fluid compressor. The scroll fluid compressor may have an orbiting whorl, a non-orbiting whorl, and a block frame which holds the orbiting whorl in contact with the non-orbiting whorl. The partial texturization can be applied on the lower surface of the orbiting whorl, the upper surface of the block frame, or both, and can include at least two first regions separated by second regions. The first regions have surfaces including a plurality of micro-cavities and the second regions have substantially smooth surfaces.
