Abstract
A method for determining the degree of coverage of a metal part having undergone a treatment modifying the surface roughness of said part, characterised in that it comprises the following steps: —a step of determining a calibration function (C) of a parameter (L*) of the CIELAB colour space as a function of the degree of coverage, in such a way as to be able to link a given value of said parameter (L*) with the corresponding value of the degree of coverage, —a step of measuring the value of said parameter (L*) of the part, and—a step of determining the degree of coverage of said part by linking, using the calibrating function, the corresponding value of the degree of coverage of the part with the value of said parameter measured in this way (L*).
