Surface hardness profile calculated from the measured wetting time tB and the specific calibration curve for the material related to the distance from the lower end of the sample and compared to the measured hardness profile. Sample: 100Cr6 dia 25 mm × 100 mm, bath: (a) distilled water, (b) polymer solution.
