Title: Advanced non-electrolytic method for metallizing a substrate by metallic salt(s) reduction and aerosol(s) projection
Inventor: STREMSDOERFER SAMUEL
IPC: C23C18/20
Filed: 2007-11-26
Abstract: The invention relates to a non-electrolytic method for metallizing a substrate of any nature by projecting an aerosol containing a solution of an oxidant metallic cation and of a reDucing agent capable of converting said cation into a metal. The purpose of the present invention is to provide a method and an advanced device for industrial and automatic chemical metallisation. This purpose is achieved by the method of the invention that comprises a preliminary step of-ap-wetting the substrate with a wetting fluid; and 60 sec at most after the end of the wetting, 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. The projection means move along a trajectory TOA between an origin point (O) and an arrival point (A) at a projection displacement speed VOA, then return to origin (O) at a projection-less displacement speed VAO along a trajectory TAO. A computing and control unit (UCC) controlling the projection means and a system for displacing said projection means is used for automating the process.
