Method for preparing a stainless steel additive coating

The present invention refers to a method for obtaining a stainless steel additive coating by deposition in a single coating process. The method of the present invention allows to compensate the dilution effect by incorporating a counteract powder to the stainless steel and, thus, obtaining the target chemical composition of the stainless steel coating. In the method of the present invention, the couteract powder is specifically tailored for the selected target stainless steel in each process. In addition, the appearance of defects and the presence of surface valleys in the coating layer is minimized.
