A method for manufacturing at least one portion of a part using successive deposition of layers, involving the steps of: a) depositing a first layer of a molten metal on a substrate such that a first metal strip is formed on the substrate; b) depositing a second layer of a molten metal on the first strip such that a second metal strip is formed on the first strip; and c) repeating steps a) and then b) for each new metal layer to be deposited on a preceding strip until the at least one portion of the part has been formed. The method may further include step d) compressing the formed bead after performing n instances of step c), n being greater than or equal to 1. The step of compressing the formed bead may be performed before the complete cooling of said bead.

Method and apparatus for manufacturing a part using successive deposition of layers

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: &#x2014;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, &#x2014;a step of measuring the value of said parameter (L*) of the part, and&#x2014;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*).
