摘要
The invention relates to a non-electrolytic method for metallizing a substrate by projecting an aerosol containing a solution of an oxidant metallic cation and of a reducing agent; said method comprising a step of -a- wetting the substrate; starting to project a metallisation according to a succession of projecting phases alternating with relaxing phases: (i) by adjusting the duration Dp of the projection phases and the duration Dr of the relaxing phases from a metallisation constant k intrinsic for each metal; and (ii) by adjusting the projection flow-rate. The metallisation projection is carried out dynamically by displacing projection means relative to the substrate in order to carry out a periodical scanning, wherein Dp correspond to the duration during which the surface unit in question is submitted to the continuous projection of the aerosol and Dr corresponds to the duration during which the part is not submitted to projection.
